pitabred -- I love the unintentional pun about my post to the alsa-dev
list -- the name I go by is Guy (my middle name :-) I have an update on
my issue. I cannot begin to remember exactly what I did, but I got
sound working at one point. I can distinctly remember making the latest
also-driver-snapshot source and typing make install-modules and on
reboot having sound. But, alas, it is now gone again. I had some serious
issues with grub (after upgrading to grub2 -- what a mistake) and the
restore process involved a lot of package purges and reinstalls. That,
of course, lost the alsa-driver modules. Just this evening I tried the
make install-modules when I noticed I didn't have sound again. And I'm
back where I was several weeks ago. No sound on the SB output. The
HDMI is correctly found. The also-dev gurus think this is a kernel
issue. So, like you I'm available for tshooting should anyone here
think I can help. I have an HP dv4 laptop:

I have no idea, of course, why purging all the kernel images, then
reinstalling the latest generic and remaking and make installing the
latest alsa-driver-snapshot doesn't work.
