Re: 2.6.10-rc2-mm3

[Paul Blazejowski <diffie@gmail.com>]

Andrew,

I have mentioned earlier, there's seems to be some kind of ALSA, udev
or sysfs issue with /dev/dsp and friends not being created under
recent mm kernels.

Last kernel that worked; 2.6.10-rc1 and i belive 2.6.9-mm1. 2.6.10-rc2
and mm3 have issues.

The odd thing is that my log shows /dev/dsp /dev/mixer being setup by
udev upon startup.

I run nForce2 based board with soundstorm audio by way of snd_intel8x0 module.

Advanced Linux Sound Architecture Driver Version 1.0.7 (Thu Nov 11
10:36:46 2004 UTC).

I use the latest version of udev-046. Is there anything else i can do
to try to debug this? as i see no errors other than /dev/dsp no such
sound device.  Playing oggs works OK though when using ALSA.

Regards,
