From: Takashi Iwai Date: Fri, 12 Oct 2012 15:24:51 +0000 (+0200) Subject: ALSA: hda - Add workaround for conflicting IEC958 controls X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=dcda5806165c155d90b9aa466a1602cf4726012b;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git ALSA: hda - Add workaround for conflicting IEC958 controls When both an SPDIF and an HDMI device are created on the same card instance, multiple IEC958 controls are created with indices=0, 1, ... But the alsa-lib configuration can't know which index corresponds actually to which PCM device, and both the SPDIF and the HDMI configurations point to the first IEC958 control wrongly. This patch introduces a (hackish and ugly) workaround: the IEC958 controls for the SPDIF device are re-labeled with device=1 when HDMI coexists. The device=1 corresponds to the actual PCM device for SPDIF, so it's anyway a better representation. In future, HDMI controls should be moved with the corresponding PCM device number, too.
