Nonexistence of /dev/sound/ and related problems.

[Verbed]

It was my intention to enable Alsa OSS emulation. Three days later-- mental exaustion. Maybe I can find some alleviation here

Profile:
1. Devfs
2. Alsa 0.90rc2
3. Emu10k1

Symptoms:
1. /dev/dsp nowhere to be found.
2. In place of the /dev/sound directory, nothingness.
3. `modprobe /dev/dsp` _does_ load snd-pcm-oss ( that also includes `ls /dev/dsp` via Devfsd )

The files look mostly the same but I'd tried altering your devfsd.conf so it's the same as mine. Other than that I'm out of suggestions since my setup worked out of the box/emerge.

[Verbed]

Altering my devfsd.conf ( including a killlall -HUP devfsd ) had little effect on the situation. Would you mind posting the contents of your /dev/sound directory? I suppose I should try remerging my system and interrogate the minds on the alsa-user mailing list.

[Verbed]

The ALSA OSS emulation on my system is now working perfectly. I suspect that I had misconfigured my kernel previously, as a reconfiguration/recompilation solved the problem.

I received a hint in the fact that my /dev/lp0 was missing as well

Congrats on getting it all working.
