Public bug reported:
I am running 10.04 kernel 2.6.32-22-generic on a Gateway MC7833u. The
sound card is an intel HDA IHC9 family. The only problem is that when I
suspend the sound will not come out of the laptop speakers. The
headphones still work fine, the mixer works fine, the internal
microphone works fine. Just no sound from the actual laptop speakers.
