Public bug reported:
Since the beginning of my experience with 12.10 beta, I have repeated
problems with the sound. Lately (beta 2, kernel 3.5.0.17.19), the
problem is that after initial boot, sound works fine, but after suspend-
resume, sound stops working. I'm using a Dell Studio 1458 laptop with
the following audio card (according to lspci): Audio device: Intel
Corporation 5 Series/3400 Series Chipset High Definition Audio (rev 05).
