I have had similar problems getting audio going in the past on IBM ThinkPads (Crystal Audio chipsets). Even my current Slackware 8.1 install doesn't work first boot. After modprobe, I get the "permission denied" error.
Until today, the quick and dirty solution has been (as root): chmod -R 777 /dev/dsp chmod -R 777 /dev/mixer I've used more conservative values in the past (such as 644), but for those not worried about the local security of your audio devices (I just want to listen to MP3s!!), it's a quick fix. Your information has been invaluable because it gives me a better way of trying to do things (adding to the audio group, etc.). A little OT, but I'll toss in that I can only play one sound source at a time (XMMS, xine, mozilla, etc.) without getting errors. When I switch sound sources, sometimes I have to modprobe the drivers again to get the new sound source to play. It seems like the driver is getting "hogged" by one sound source, and then won't let go. But I have no clue as to why. Any thoughts?
