So the card appears to be there and I get no errors in dmesg like a lot of other people are getting.

I was certain it must be a volume thing but all the levels are maxed in alsamixer and all channels are unmuted.  One weird thing though: I have no master channel?

I have not been able to try an old kernel yet.  This is a new system though and while I think I had sound working once it's not like it suddenly broke.

What does the Chip: section say in alsamixer?

Re: No sound in 2.6.19 with Intel Chipset

I have fixed it.  I needed to add:

options snd-hda-intel model=3stack

to /etc/modprobe.conf

Not really sure why but it works.  I just googled for google:p5ld2-se intel hda

Re: No sound in 2.6.19 with Intel Chipset

The snd-hda-intel driver supports a lot of different "codecs" for the sound chip, for different chip producers, I think. And even each codec sometimes has many different variants. The alsa developers have a big job of catching up with all the new variants coming with each new laptop.
