Hi, I have this soundcard: Bus 0, device 13, function 0: Multimedia audio controller: C-Media Electronics Inc CM8338A (rev 16). IRQ 5. Master Capable. Latency=64. Min Gnt=2.Max Lat=24. I/O at 0xe400 [0xe4ff].
And using the cmpci driver. The problem is, mostly the sound is nogood, most sound comes from one speaker, and it just sounds completly screwd up. Atleast with most programs shuch as xmms, mplayer, most games. However with mpg123 and ogg123 it sounds fine. Now, for the programs which i can set to run in 8 bit modus (e.g. esd -b, artsd -b 8 ) the sound is also fine. Is this really an 8 bit soundcard ? What troubles me is that with a 2.4.2 kernel(at least the one from Redhat, 7.2 I believe it was ), I didn't have to do anything special, the sound was always ok. The next kernel I tried was 2.4.5, not ok, Now running 2.4.20-pre11, same problems here, so I installed ALSA and with its snd-cmipci driver sound is alwasy fine, so I do think there is something fishy with the cmpci driver...
