[MacBook1,1, SigmaTel STAC9221 A1, White Headphone Out, Left] No sound at all

[Simon Mewes]

I just installed Ubuntu 12.4 and laptop speakers worked out of the box at first.

Headphones do not work at all, and now that I tried to put them in, laptop speaker sound also ceased to function. Test sounds in sound settings are not audible. I do get the ubuntu startup sound on the login screen after I restart the computer, so it's not a physical problem.

I tried to use alsamixer to unmute all channels without any effect at all.

Thanks for your attention.

I have solved the problem. In the "Sound Settings" Window, I had erroneously selected "Digital Output (S/PDIF)" instead of "Speaker"/"Headphones".

Again, thank you for your attention. Sorry for the trouble.

Marking Incomplete since it was an issue with your configuration which you claim to have solved. If the issue is really solved, then leave this bug report alone and it will expire in 60 days. If you continue to have issues, set the bug back to New.
