2 | Advanced Linux Sound Architecture - Driver | |
3 | ========================================== | |
4 | Configuration guide | |
5 | ||
6 | ||
7 | Kernel Configuration | |
8 | ==================== | |
9 | ||
10 | To enable ALSA support you need at least to build the kernel with | |
11 | primary sound card support (CONFIG_SOUND). Since ALSA can emulate OSS, | |
12 | you don't have to choose any of the OSS modules. | |
13 | ||
14 | Enable "OSS API emulation" (CONFIG_SND_OSSEMUL) and both OSS mixer and | |
15 | PCM supports if you want to run OSS applications with ALSA. | |
16 | ||
17 | If you want to support the WaveTable functionality on cards such as | |
18 | SB Live! then you need to enable "Sequencer support" | |
19 | (CONFIG_SND_SEQUENCER). | |
20 | ||
21 | To make ALSA debug messages more verbose, enable the "Verbose printk" | |
22 | and "Debug" options. To check for memory leaks, turn on "Debug memory" | |
23 | too. "Debug detection" will add checks for the detection of cards. | |
24 | ||
25 | Please note that all the ALSA ISA drivers support the Linux isapnp API | |
26 | (if the card supports ISA PnP). You don't need to configure the cards | |
27 | using isapnptools. | |
28 | ||
29 | ||
30 | Creating ALSA devices | |
31 | ===================== | |
32 | ||
33 | This depends on your distribution, but normally you use the /dev/MAKEDEV | |
34 | script to create the necessary device nodes. On some systems you use a | |
35 | script named 'snddevices'. | |
36 | ||
37 | ||
38 | Module parameters | |
39 | ================= | |
40 | ||
41 | The user can load modules with options. If the module supports more than | |
42 | one card and you have more than one card of the same type then you can | |
43 | specify multiple values for the option separated by commas. | |
44 | ||
45 | Prior to version 0.9.0rc4 options had a 'snd_' prefix. This was removed. | |
46 | ||
47 | Module snd | |
48 | ---------- | |
49 | ||
50 | The core ALSA module. It is used by all ALSA card drivers. | |
51 | It takes the following options which have global effects. | |
52 | ||
53 | major - major number for sound driver | |
54 | - Default: 116 | |
55 | cards_limit | |
56 | - limiting card index for auto-loading (1-8) | |
57 | - Default: 1 | |
58 | - For auto-loading more than one card, specify this | |
59 | option together with snd-card-X aliases. | |

61 | ||
62 | Module snd-pcm-oss | |
63 | ------------------ | |
64 | ||
65 | The PCM OSS emulation module. | |
66 | This module takes options which change the mapping of devices. | |
67 | ||
68 | dsp_map - PCM device number maps assigned to the 1st OSS device. | |
69 | - Default: 0 | |
70 | adsp_map - PCM device number maps assigned to the 2st OSS device. | |
71 | - Default: 1 | |
72 | nonblock_open | |
6243008b | 73 | - Don't block opening busy PCM devices. Default: 1 |
1da177e4 LT |
74 | |
75 | For example, when dsp_map=2, /dev/dsp will be mapped to PCM #2 of | |
76 | the card #0. Similarly, when adsp_map=0, /dev/adsp will be mapped | |
77 | to PCM #0 of the card #0. | |
78 | For changing the second or later card, specify the option with | |
79 | commas, such like "dsp_map=0,1". | |
80 | ||
81 | nonblock_open option is used to change the behavior of the PCM | |
82 | regarding opening the device. When this option is non-zero, | |
83 | opening a busy OSS PCM device won't be blocked but return | |
84 | immediately with EAGAIN (just like O_NONBLOCK flag). | |
85 | ||
86 | Module snd-rawmidi | |
87 | ------------------ | |
88 | ||
89 | This module takes options which change the mapping of devices. | |
90 | similar to those of the snd-pcm-oss module. | |
91 | ||
92 | midi_map - MIDI device number maps assigned to the 1st OSS device. | |
93 | - Default: 0 | |
94 | amidi_map - MIDI device number maps assigned to the 2st OSS device. | |
95 | - Default: 1 | |
96 | ||
97 | Common parameters for top sound card modules | |
98 | -------------------------------------------- | |
99 | ||
100 | Each of top level sound card module takes the following options. | |
101 | ||
102 | index - index (slot #) of sound card | |
0ef797c5 | 103 | - Values: 0 through 31 or negative |
1da177e4 LT |
104 | - If nonnegative, assign that index number |
105 | - if negative, interpret as a bitmask of permissible | |
106 | indices; the first free permitted index is assigned | |
107 | - Default: -1 | |
108 | id - card ID (identifier or name) | |
109 | - Can be up to 15 characters long | |
110 | - Default: the card type | |
111 | - A directory by this name is created under /proc/asound/ | |
112 | containing information about the card | |
113 | - This ID can be used instead of the index number in | |
114 | identifying the card | |
115 | enable - enable card | |
116 | - Default: enabled, for PCI and ISA PnP cards | |

118 | Module snd-adlib |
119 | ---------------- | |
120 | ||
121 | Module for AdLib FM cards. | |
122 | ||
123 | port - port # for OPL chip | |
124 | ||
125 | This module supports multiple cards. It does not support autoprobe, so | |
126 | the port must be specified. For actual AdLib FM cards it will be 0x388. | |
127 | Note that this card does not have PCM support and no mixer; only FM | |
128 | synthesis. | |
129 | ||
130 | Make sure you have "sbiload" from the alsa-tools package available and, | |
131 | after loading the module, find out the assigned ALSA sequencer port | |
132 | number through "sbiload -l". Example output: | |
133 | ||
134 | Port Client name Port name | |
135 | 64:0 OPL2 FM synth OPL2 FM Port | |
136 | ||
137 | Load the std.sb and drums.sb patches also supplied by sbiload: | |
138 | ||
139 | sbiload -p 64:0 std.sb drums.sb | |
140 | ||
141 | If you use this driver to drive an OPL3, you can use std.o3 and drums.o3 | |
142 | instead. To have the card produce sound, use aplaymidi from alsa-utils: | |
143 | ||
144 | aplaymidi -p 64:0 foo.mid | |
145 | ||

927 | The model name "genric" is treated as a special case. When this |
928 | model is given, the driver uses the generic codec parser without | |
929 | "codec-patch". It's sometimes good for testing and debugging. | |
930 | ||
6243008b TI |
931 | If the default configuration doesn't work and one of the above |
932 | matches with your device, report it together with the PCI | |
933 | subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel | |
934 | ML (see the section "Links and Addresses"). | |
935 | ||
c74db86b TI |
936 | Note 2: If you get click noises on output, try the module option |
937 | position_fix=1 or 2. position_fix=1 will use the SD_LPIB | |
938 | register value without FIFO size correction as the current | |
939 | DMA pointer. position_fix=2 will make the driver to use | |
940 | the position buffer instead of reading SD_LPIB register. | |
941 | (Usually SD_LPLIB register is more accurate than the | |
942 | position buffer.) | |
943 | ||
27346166 TI |
944 | NB: If you get many "azx_get_response timeout" messages at |
945 | loading, it's likely a problem of interrupts (e.g. ACPI irq | |
946 | routing). Try to boot with options like "pci=noacpi". Also, you | |
947 | can try "single_cmd=1" module option. This will switch the | |
948 | communication method between HDA controller and codecs to the | |
949 | single immediate commands instead of CORB/RIRB. Basically, the | |
950 | single command mode is provided only for BIOS, and you won't get | |
951 | unsolicited events, too. But, at least, this works independently | |
952 | from the irq. Remember this is a last resort, and should be | |
953 | avoided as much as possible... | |

969 | ||
970 | Note: snd-page-alloc module does the job which snd-hammerfall-mem | |
971 | module did formerly. It will allocate the buffers in advance | |
972 | when any HDSP cards are found. To make the buffer | |
973 | allocation sure, load snd-page-alloc module in the early | |

1da177e4 | 1323 | |
8a3fb4d0 | 1324 | This module supports one chip and autoprobe. |
1da177e4 LT |
1325 | |
1326 | The power-management is supported. | |
1327 | ||
1328 | Note: on some notebooks the buffer address cannot be detected | |
1329 | automatically, or causes hang-up during initialization. | |
fff9289b ML |
1330 | In such a case, specify the buffer top address explicitly via |
1331 | the buffer_top option. | |
1da177e4 LT |
1332 | For example, |
1333 | Sony F250: buffer_top=0x25a800 | |
1334 | Sony F270: buffer_top=0x272800 | |
1335 | The driver supports only ac97 codec. It's possible to force | |
1336 | to initialize/use ac97 although it's not detected. In such a | |
1337 | case, use force_ac97=1 option - but *NO* guarantee whether it | |
1338 | works! | |
1339 | ||
1340 | Note: The NM256 chip can be linked internally with non-AC97 | |
1341 | codecs. This driver supports only the AC97 codec, and won't work | |
1342 | with machines with other (most likely CS423x or OPL3SAx) chips, | |
1343 | even though the device is detected in lspci. In such a case, try | |
1344 | other drivers, e.g. snd-cs4232 or snd-opl3sa2. Some has ISA-PnP | |
6243008b | 1345 | but some doesn't have ISA PnP. You'll need to specify isapnp=0 |
1da177e4 LT |
1346 | and proper hardware parameters in the case without ISA PnP. |
1347 | ||
1348 | Note: some laptops need a workaround for AC97 RESET. For the | |
1349 | known hardware like Dell Latitude LS and Sony PCG-F305, this | |
1350 | workaround is enabled automatically. For other laptops with a | |
1351 | hard freeze, you can try reset_workaround=1 option. | |
1352 | ||
d1f38cf9 TI |
1353 | Note: Dell Latitude CSx laptops have another problem regarding |
1354 | AC97 RESET. On these laptops, reset_workaround2 option is | |
1355 | turned on as default. This option is worth to try if the | |
1356 | previous reset_workaround option doesn't help. | |
1357 | ||
1da177e4 LT |
1358 | Note: This driver is really crappy. It's a porting from the |
1359 | OSS driver, which is a result of black-magic reverse engineering. | |
1360 | The detection of codec will fail if the driver is loaded *after* | |
1361 | X-server as described above. You might be able to force to load | |
1362 | the module, but it may result in hang-up. Hence, make sure that | |
1363 | you load this module *before* X if you encounter this kind of | |
1364 | problem. | |

1da177e4 | 1728 | |
b7fe4622 | 1729 | This module supports one chip and autoprobe. |
1da177e4 LT |
1730 | |
1731 | Note: on some SMP motherboards like MSI 694D the interrupts might | |
1732 | not be generated properly. In such a case, please try to | |
1733 | set the SMP (or MPS) version on BIOS to 1.1 instead of | |
1734 | default value 1.4. Then the interrupt number will be | |
1735 | assigned under 15. You might also upgrade your BIOS. | |
1736 | ||
2d7eb7cb | 1737 | Note: VIA8233/5/7 (not VIA8233A) can support DXS (direct sound) |
1da177e4 | 1738 | channels as the first PCM. On these channels, up to 4 |
2d7eb7cb SV |
1739 | streams can be played at the same time, and the controller |
1740 | can perform sample rate conversion with separate rates for | |
1741 | each channel. | |
1da177e4 LT |
1742 | As default (dxs_support = 0), 48k fixed rate is chosen |
1743 | except for the known devices since the output is often | |
1744 | noisy except for 48k on some mother boards due to the | |
1745 | bug of BIOS. | |
2d7eb7cb | 1746 | Please try once dxs_support=5 and if it works on other |
1da177e4 LT |
1747 | sample rates (e.g. 44.1kHz of mp3 playback), please let us |
1748 | know the PCI subsystem vendor/device id's (output of | |
1749 | "lspci -nv"). | |
cdc27f3a TI |
1750 | If dxs_support=5 does not work, try dxs_support=4; if it |
1751 | doesn't work too, try dxs_support=1. (dxs_support=1 is | |
6243008b | 1752 | usually for old motherboards. The correct implemented |
cdc27f3a | 1753 | board should work with 4 or 5.) If it still doesn't |
1da177e4 LT |
1754 | work and the default setting is ok, dxs_support=3 is the |
1755 | right choice. If the default setting doesn't work at all, | |
1756 | try dxs_support=2 to disable the DXS channels. | |
1757 | In any cases, please let us know the result and the | |
6243008b TI |
1758 | subsystem vendor/device ids. See "Links and Addresses" |
1759 | below. | |
1da177e4 LT |
1760 | |
1761 | Note: for the MPU401 on VIA823x, use snd-mpu401 driver | |
6243008b | 1762 | additionally. The mpu_port option is for VIA686 chips only. |

1792 | ---------------- | |
1793 | ||
1794 | Module for Digigram VX-Pocket VX222, V222 v2 and Mic cards. | |
1795 | ||
1796 | mic - Enable Microphone on V222 Mic (NYI) | |
1797 | ibl - Capture IBL size. (default = 0, minimum size) | |
1798 | ||
0ef797c5 | 1799 | This module supports multiple cards. |
1da177e4 LT |
1800 | |
1801 | When the driver is compiled as a module and the hotplug firmware | |
1802 | is supported, the firmware data is loaded via hotplug automatically. | |
1803 | Install the necessary firmware files in alsa-firmware package. | |
1804 | When no hotplug fw loader is available, you need to load the | |
1805 | firmware via vxloader utility in alsa-tools package. To invoke | |
1806 | vxloader automatically, add the following to /etc/modprobe.conf | |
1807 | ||
1808 | install snd-vx222 /sbin/modprobe --first-time -i snd-vx222 && /usr/bin/vxloader | |
1809 | ||
1810 | (for 2.2/2.4 kernels, add "post-install /usr/bin/vxloader" to | |
1811 | /etc/modules.conf, instead.) | |
1812 | IBL size defines the interrupts period for PCM. The smaller size | |
1813 | gives smaller latency but leads to more CPU consumption, too. | |
1814 | The size is usually aligned to 126. As default (=0), the smallest | |
1815 | size is chosen. The possible IBL values can be found in | |
1816 | /proc/asound/cardX/vx-status proc file. | |

1824 | |
1825 | ibl - Capture IBL size. (default = 0, minimum size) | |
1826 | ||
0ef797c5 | 1827 | This module supports multiple cards. The module is compiled only when |
1da177e4 LT |
1828 | PCMCIA is supported on kernel. |
1829 | ||
6243008b TI |
1830 | With the older 2.6.x kernel, to activate the driver via the card |
1831 | manager, you'll need to set up /etc/pcmcia/vxpocket.conf. See the | |
1832 | sound/pcmcia/vx/vxpocket.c. 2.6.13 or later kernel requires no | |
1833 | longer require a config file. | |
1da177e4 LT |
1834 | |
1835 | When the driver is compiled as a module and the hotplug firmware | |
1836 | is supported, the firmware data is loaded via hotplug automatically. | |
1837 | Install the necessary firmware files in alsa-firmware package. | |
1838 | When no hotplug fw loader is available, you need to load the | |
1839 | firmware via vxloader utility in alsa-tools package. | |

1873 | AC97 Quirk Option |
1874 | ================= | |
1875 | ||
1876 | The ac97_quirk option is used to enable/override the workaround for | |
1877 | specific devices on drivers for on-board AC'97 controllers like | |
1878 | snd-intel8x0. Some hardware have swapped output pins between Master | |
1879 | and Headphone, or Surround (thanks to confusion of AC'97 | |
1880 | specifications from version to version :-) | |
1881 | ||
1882 | The driver provides the auto-detection of known problematic devices, | |
1883 | but some might be unknown or wrongly detected. In such a case, pass | |
1884 | the proper value with this option. | |
1885 | ||
1886 | The following strings are accepted: | |
1887 | - default Don't override the default setting | |
10e4097f | 1888 | - none Disable the quirk |
6243008b TI |
1889 | - hp_only Bind Master and Headphone controls as a single control |
1890 | - swap_hp Swap headphone and master controls | |
1891 | - swap_surround Swap master and surround controls | |
1892 | - ad_sharing For AD1985, turn on OMS bit and use headphone | |
1893 | - alc_jack For ALC65x, turn on the jack sense mode | |
1894 | - inv_eapd Inverted EAPD implementation | |
1895 | - mute_led Bind EAPD bit for turning on/off mute LED | |
1896 | ||
1897 | For backward compatibility, the corresponding integer value -1, 0, | |
1898 | ... are accepted, too. | |
1899 | ||
1900 | For example, if "Master" volume control has no effect on your device | |
1901 | but only "Headphone" does, pass ac97_quirk=hp_only module option. | |
1902 | ||
1903 | ||
1da177e4 LT |
1904 | Configuring Non-ISAPNP Cards |
1905 | ============================ | |
1906 | ||
1907 | When the kernel is configured with ISA-PnP support, the modules | |
1908 | supporting the isapnp cards will have module options "isapnp". | |
1909 | If this option is set, *only* the ISA-PnP devices will be probed. | |
1910 | For probing the non ISA-PnP cards, you have to pass "isapnp=0" option | |
1911 | together with the proper i/o and irq configuration. | |
1912 | ||
1913 | When the kernel is configured without ISA-PnP support, isapnp option | |
1914 | will be not built in. | |
1915 | ||
1916 | ||
1917 | Module Autoloading Support | |
1918 | ========================== | |
1919 | ||
1920 | The ALSA drivers can be loaded automatically on demand by defining | |
1921 | module aliases. The string 'snd-card-%1' is requested for ALSA native | |
1922 | devices where %i is sound card number from zero to seven. | |
1923 | ||
1924 | To auto-load an ALSA driver for OSS services, define the string | |
1925 | 'sound-slot-%i' where %i means the slot number for OSS, which | |
1926 | corresponds to the card index of ALSA. Usually, define this | |
d533f671 | 1927 | as the same card module. |
1da177e4 LT |
1928 | |
1929 | An example configuration for a single emu10k1 card is like below: | |
1930 | ----- /etc/modprobe.conf | |
1931 | alias snd-card-0 snd-emu10k1 | |
1932 | alias sound-slot-0 snd-emu10k1 | |
1933 | ----- /etc/modprobe.conf | |
1934 | ||
1935 | The available number of auto-loaded sound cards depends on the module | |
1936 | option "cards_limit" of snd module. As default it's set to 1. | |
1937 | To enable the auto-loading of multiple cards, specify the number of | |
1938 | sound cards in that option. | |
1939 | ||
1940 | When multiple cards are available, it'd better to specify the index | |
1941 | number for each card via module option, too, so that the order of | |
1942 | cards is kept consistent. | |
1943 | ||
1944 | An example configuration for two sound cards is like below: | |
1945 | ||
1946 | ----- /etc/modprobe.conf | |
1947 | # ALSA portion | |
1948 | options snd cards_limit=2 | |
1949 | alias snd-card-0 snd-interwave | |
1950 | alias snd-card-1 snd-ens1371 | |
1951 | options snd-interwave index=0 | |
1952 | options snd-ens1371 index=1 | |
1953 | # OSS/Free portion | |
1954 | alias sound-slot-0 snd-interwave | |
1955 | alias sound-slot-1 snd-ens1371 | |
2fe0ae78 | 1956 | ----- /etc/modprobe.conf |
1da177e4 LT |
1957 | |
1958 | In this example, the interwave card is always loaded as the first card | |
1959 | (index 0) and ens1371 as the second (index 1). | |
1960 | ||
1961 | ||
1962 | ALSA PCM devices to OSS devices mapping | |

1973 | /dev/snd/pcmC2D1[c|p] -> /dev/adsp2 -> minor 12+32 = 44 | |
1974 | ||
1975 | The first number from /dev/snd/pcmC{X}D{Y}[c|p] expression means | |
1976 | sound card number and second means device number. The ALSA devices | |
1977 | have either 'c' or 'p' suffix indicating the direction, capture and | |
1978 | playback, respectively. | |
1979 | ||
1980 | Please note that the device mapping above may be varied via the module | |
1981 | options of snd-pcm-oss module. | |

1984 | Proc interfaces (/proc/asound) |
1985 | ============================== | |
1986 | ||
1987 | /proc/asound/card#/pcm#[cp]/oss | |
1988 | ------------------------------- | |
1989 | String "erase" - erase all additional informations about OSS applications | |
1990 | String "<app_name> <fragments> <fragment_size> [<options>]" | |
1991 | ||
1992 | <app_name> - name of application with (higher priority) or without path | |
1993 | <fragments> - number of fragments or zero if auto | |
1994 | <fragment_size> - size of fragment in bytes or zero if auto | |
1995 | <options> - optional parameters | |
1996 | - disable the application tries to open a pcm device for | |
1997 | this channel but does not want to use it. | |
1998 | (Cause a bug or mmap needs) | |
1999 | It's good for Quake etc... | |
2000 | - direct don't use plugins | |
2001 | - block force block mode (rvplayer) | |
2002 | - non-block force non-block mode | |
2003 | - whole-frag write only whole fragments (optimization affecting | |
2004 | playback only) | |
2005 | - no-silence do not fill silence ahead to avoid clicks | |

2006 | - buggy-ptr Returns the whitespace blocks in GETOPTR ioctl |
2007 | instead of filled blocks | |

2014 | Early Buffer Allocation |
2015 | ======================= | |
2016 | ||
2017 | Some drivers (e.g. hdsp) require the large contiguous buffers, and | |
2018 | sometimes it's too late to find such spaces when the driver module is | |
2019 | actually loaded due to memory fragmentation. You can pre-allocate the | |
2020 | PCM buffers by loading snd-page-alloc module and write commands to its | |
2021 | proc file in prior, for example, in the early boot stage like | |
2022 | /etc/init.d/*.local scripts. | |
2023 | ||
2024 | Reading the proc file /proc/drivers/snd-page-alloc shows the current | |
2025 | usage of page allocation. In writing, you can send the following | |
2026 | commands to the snd-page-alloc driver: | |
2027 | ||
2028 | - add VENDOR DEVICE MASK SIZE BUFFERS | |
2029 | ||
2030 | VENDOR and DEVICE are PCI vendor and device IDs. They take | |
2031 | integer numbers (0x prefix is needed for the hex). | |
2032 | MASK is the PCI DMA mask. Pass 0 if not restricted. | |
2033 | SIZE is the size of each buffer to allocate. You can pass | |
2034 | k and m suffix for KB and MB. The max number is 16MB. | |
2035 | BUFFERS is the number of buffers to allocate. It must be greater | |
2036 | than 0. The max number is 4. | |
2037 | ||
2038 | - erase | |
2039 | ||
2040 | This will erase the all pre-allocated buffers which are not in | |
2041 | use. | |
