my first mixer use useless. you can change parameters but it has no
effect on playing sounds
my second mixer works in a very very strange manner e.g. if you rise
master-volume, cd-volume mutes
I would signify these mixer "unusable"

Not working: mixer!

I tried 0.9beta5 - status:
compiling and installing worked without problems, modules are loaded
(even oss-modules)
there is only one mixer and it's working perfect, but:
playing files (wav, mp3, au, etc) doesn't work. I've tried different
player (aplay, play, also oss-player)
and all I get is a "pcm-device unknown" on different pcm-devices
yet, because mixer is working, you can play cd's or sound from external
input

hmmm, OSS is working with my CMI8330, even playing CD or external input,
full-duplex never tried ...
I'm using OSS from SuSE 6.4 (it's free for SuSE customers, but it's only
available
for ISA-soundcards and it's only working with SuSE-kernel 2.2.14
if you try to update kernel (e.g. 2.2.18 or 2.2.19 ...) oss is no longer
working!!
