Hi,

Same problem here... (info below)... Updated from feisty to hardy RC...
Now snd-hda modules aren't working and I have no sound card detected at
all.

Of course they used to work like a charm, otherwise I wouldn't be
posting here !

My host is a dell laptop XPS M1710

- rt kernel do give sound... OK
- my old kernel (from feisty) has sound as well... OK
[however, a lot of things like my GPU are not usable anymore with those two 
kernels... and I guess you definitely want to fix this bug because hda drivers 
are somewhat popular and you can't afford to break them can you ?!]
