Modular sound seems buggy in 2.2.0-pre5 Everything is fine if sound is compiled into the kernel, giving me 16-bit sound on /dev/dsp and 8-bit on /dev/dsp1.
I have the modules pas2 (16-bit proaudio sound) and sb (8-bit mono sb-compatibility stuff on the proaudio card)
In the beginning lsmod showed no sound modules as expected. "modprobe pas2" worked and let me cat files to /dev/dsp for sound "modprobe sb" didn't work for /dev/dsp1, could be a configuration problem. Then I tried to remove all sound modules, and a bug showed up: "soundcore" remained with a usage count of 1. "modprobe pas2" made 16-bit sound work again, but this time on /dev/dsp1. /dev/dsp didn't work, I guessed this had something to do with the wrong usage count for soundcore. "modprobe sb" again made no difference. I then removed the sound modules again, and soundcore was again stuck with a bogus usage count of 1. catting a file to /dev/dsp without any driver loaded didn't produce the expected "operation not supported", I got an OOPS (unable to handle kernel paging request) and so on. I guess there was an attempt to use the driver module that wasn't there.
I post this in case someone is working on the sound drivers for 2.2.0 I'll try to find out more when I get the time.
