It mustn't be the kernel
Last change in hda-intel code in in pre-2.6.23-rc1
by the way, PCM control is not hardware control
it is a softvol plug-in
I wasn't paying a lot of attention when the changed happen. I upgraded
the kernel and when it booted all of my sound was missing. I played
around with it until I determined that the sound was still there but
at very low volumes.
I'm running Ubuntu 7.04 64b. Nothing special, using the default audio
install. I am compiling and installing my own kernels.
Are these entries with all the zeros normal?
