Subject: [gentoo-user] mdev: sound is only working some of the time.
Date: Tue, 20 Mar 2012 22:31:08 +0000 [thread overview]

Hi, all.
Got a problem with my system running under mdev. When I try to play CDs
(with aqualung feeding into PulseAudio), no sound comes out. However,
when I listen to an audio section from a newspaper page such as
www.tagesschau.de (no idea what audio format) it works.
Clearly this is something to do with mdev. I had a look at the devices
in /dev, searching for those in group audio. Under udev, I find the
following as device nodes:
adsp audio dsp mixer mixer1 sequencer sequencer2.
Under mdev, all of these bar one are symlinks into the real nodes in a
subdirectory. The odd man out is mixer1 which is a device node, but
with owner/group begin root/root (rather than root/audio).
Can anybody suggest any fix, or further areas of exploration? Thanks!
