[Alsa-user] Volume fading out

[paul c. <pau...@gm...>]

I've set up two PCs to transfer an audio feed from one place to
another over a wireless network link. One reads the audio, encodes it
to Ogg Vorbis using ices2 and icecast2 and sends it over the network
to the other, which plays it back using ogg123.

The problem is at the playback end. Over a period of time, the output
volume reduces gradually. The changing volume doesn't reflect in
alsamixer, but is noticeable when listening. Running alsactl restore
doesn't fix the problem, but adjusting the PCM mixer either through
alsamixer or amixer causes it to restore instantly to the correct
level.

ALSA is version 1.08 running on kernel 2.6.11. The soundcards at each
end are Digigram VX222v2 professional cards. The good people at
Digigram are working on this, but don't seem to be too experienced
with Linux.

Any ideas?
