[alsa-devel] ALSA: Sound barely audible since 2.6.37-rc1+
Hi Takashi,
The sound on my computer since 2.6.37-rc1+ is barely audible (extremely soft), The sound remains the same even on increasing it on the desktop or the application.
On accessing alsa-mixer I get the error, cannot load mixer controls: Invalid argument.
I bisected the problem to this commit.
03b7a1ab557efe34e8f79b78660e514bd7374248 is the first bad commit commit 03b7a1ab557efe34e8f79b78660e514bd7374248 Author: David Henningsson david.henningsson@canonical.com Date: Tue Nov 9 14:35:30 2010 +0100
ALSA: HDA: Create mixers on ALC887
BugLink: http://launchpad.net/bugs/669092
ALC887 does not have any volume control ability on the mixer NIDs, so put the volume controls on the dac NIDs instead. Without this patch, ALC887 users cannot use alsamixer at all.

Could you get alsa-info.sh output (run with --no-upload option) on the old working kernel? If so, please attach the output. Anyway, please give alsa-info.sh output on the broken kernel, too.
thanks,
Takashi

This patch was actually dropped (see 625787b760b920234ba9736a1ef85297e1bfa110 ) in favour of 01e0f1378c47947b825eac05c98697ab1be1c86f (ALSA: hda - Fixed ALC887-VD initial error).
