OK, I think my configuration is really... wierd ;)

I have:
Event Gina20, using the snd-echoaudio alsa driver written by Giuliano Pochini (works fine on its own)
some via onboard thingy, using the snd-via82xx driver (works fine on its own)


To make anything more complicated, I also have an Hauppauge WinTV, which has an audio mixer/direct record device supported by a kernel module (btaudio), which registers /dev/dsp, /dev/dsp1 and /dev/mixer.

But forget that TV card.

Even with only the two alsa cards I have the problem that, if I try to load both cards' modules, I get all the pcm-devices:
/dev/snd:
pcmC0D0c, pcmC0D0p, pcmC1D0c, ....


for both cards - but only one mixer device is available!
/dev/snd/controlC0

That's the first problem. The second is that I need to control volume via the oss emulation, and if the btaudio module is loaded, the snd-mixer-oss module complains (via dmesg) that it cannot lock the mixer resource 0:0 (which is no doubt true because there sits the mixer of the hauppauge card!)

The first problem is more urgent because I really need both cards working at the same time... :(

thanks for suggestions,
 Lars
