No /dev/dsp /dev/mixer etc
 
I thought my sound subsystem was fine until I tried installing Skype. System is Mandriva 10.2 (upgraded from 10.1 and 10.0) with a nforce 2 integrated sound chip. My microphone plays fine through the speakers but I don't get any sound in Skype and on chasing the probem around I also don't get any recorded sound using arecord.

Other interesting but maybe relavant stuff:
I don't have any /dev/dsp or /dev/mixer.
I don't have any /dev/sound devices
I do use udev and it has got the following devices under /dev/snd but i don't know what they are or do...

When running skype from the terminal I get a read error on /dev/dsp (not surprisingly), when running it with "artsdsp -m /usr/bin/skype" it runs fine except no audio from the mic. and artsdsp complains about no /dev/mixer.

All oss emulation modules appear loaded ok.

I get a boot error message complaining about lack of mixer settings. KDE 3.3 appears to have normal mixer controls and they appear to be working ok.

Not sure where to go from here.

David

Why don't you install ALSA????

I try it and works very good, exept in case that you run two or more app at the same time. it returns some error.
well, i found (on their home page) some plug in. i have not test it yet!

I beleive it is installed already - It is compiled as a kernel module.
