Subject: [gentoo-user] mdev: sound is only working some of the time.
Date: Tue, 20 Mar 2012 22:31:08 +0000	[thread overview]
Message-ID: <20120320223107.GA2961@acm.acm> (raw)

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!
