On my Sony Vaio VGN-FZ140E I've got the same problem. No sound on the headphones and the speaker doesn't turn off when I plug in the phone.
The modifications suggested didn't work... I still got the sound out of the speakers and now sound on the phones. lspci shows: 00:1b.0 Audio device: Intel Corporation 82801H (ICH8 Family) HD Audio Controller (rev 03) -- Sound not configured properly on Sony Vaios using snd_hda_intel https://bugs.launchpad.net/bugs/195605 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
