Hi all,


I have been using kernel 2.6 from arjan rpms site sice 2.6-test4 and
they work great! thanks arjan.


Up to kernel 2.6 test7, sound was working ok with no errors. Some time later, I updated to test11 and now to final 2.6.0-1.104 and I'm now getting on my volume control:

"Couldn't open mixer device /dev/sound/mixer"


Somewhere around test8, they changed the way kernel refers to character devices. Previously kernel tried to load char-major-xx, but now it tries char-major-xx-yy (where xx is a major device number and yy is minor number).


You should change in /etc/modprobe.conf line

alias char-major-14 <something>
to
alias char-major-14-* <something>

to make it work.



whenever I start the desktop.

I found some helpful tips here:
http://linuxquestions.org/questions/history/120468

and so, my sound now just works if I do modprobe snd-mixer-oss.

I'd like to know what changed from test-7 to test11 and final and what
could I do to have the sound mixer working again.

Also, if it is related, instructions for getting ALSA working with this
new kernel are very welcome!

Thanks in advance.

Francisco Figueiredo Jr.
