ALSA lib pcm_hw.c:1155:(snd_pcm_hw_open) open /dev/snd/pcmC0D0p failed: No such file

bash-2.05b$ lsmod
Module Size Used by
snd_intel8x0 30024 0

snd_mpu401_uart 6144 1 snd_intel8x0

snd_pcm_oss is the part about backwards oss compatability..

when you install alsa seperatly from the kernel, you are supplied with a snddevices script that alters the enteries in /dev/ for alsa... is there no such script in the kernel tree ?

try installing the latest version of alsa, (from dourceforge)
be sure to read ./configure --help when comiling alsa-drivers for info on how to enable oss.

It worked before

The thing is the sound worked out-of-the-box , but I installed the latest nvidia nforce sound drivers instead.
but they didn't quite work so I decided togo back to the snd_intel8x0 . but now it doesn't work
Now it's giving me all those errors..
should I really have to mess around with /dev files when using udev ?

snd_pcm_oss
snd_something_mixer

are the two modules unable to load at boot time.
seeing it says snd_PCM_oss gives you a hint that they are responsible for the /dev/snd/pcm* or am I totally wrong?!
I just can't seem to find the modules in the kernel config..

what happens when you try to modprobe these modules ?

your totally wrong....... snd_pcm_oss gives the old /dev/dsp pcm interface...
you only need that if you have some reeeealy old software that still relies on OSS.
