Comment 14 for bug 134252

Audio is working again for me too after some kernel(-module)-related updates.

A side note for people having trouble with fglrx: after getting trouble with the fglrx module delivered with the linux-restricted package I compiled the newest 8.40.4 driver from source packages that one can generate with the ati installer (also for gutsy now). Since then everything is working fine again. Only thing to remember is that you _have_ to run sudo depmod -a manually after installation of the module.
