Comment 8 for bug 546769

Same problem, thank you so much for your solution, Pistolpete - worked GREAT.

Haven't tried the patch yet, but, yeah, the HDA Analyzer does the trick.

Sony VPCB1 running maverick - no sound until I followed your suggestion, had tried various meaningless things such as:
* options snd-hda-intel model=auto
* setting any of the options in sound preferences profiles (the various analog and hdmi ones) - actually, when I accidentally selected the input profile, my entire desktop locked up using 100% CPU until I restarted gdm from a VT - btw, it does that if you kill pulseaudio too - it didn't use to
* testing mplayer with: oss alsa esd pulse nas sdl openal
* making sure all channels were at 100% in alsamixer and unmuted (they are)
* plugging a set of external speakers into the headphone jack
* testing the various connectors under output in sound preferences.

all wild shots in the dark. thank you!

Now, I wonder why this is still an issue almost 5 months after a reported solution...
