From 36c7b833e5d2501142a371e4e75281d3a29fbd6b Mon Sep 17 00:00:00 2001 From: Viral Mehta Date: Tue, 10 Mar 2009 15:43:18 +0100 Subject: [PATCH] ALSA: oss-mixer - Fixes recording gain control At the time of initialization, SNDRV_MIXER_OSS_PRESENT_PVOLUME bit is not set for MIC (slot 7). So, the same should not be checked when an application tries to do gain control for audio recording devices. Just check slot->present for SNDRV_MIXER_OSS_PRESENT_CVOLUME independently. Verified with a simple application which opens /dev/dsp for recording and /dev/mixer for volume control. Have tested two usb audio mic devices.
