I'm seeing a similar problem here. It didn't happen on a particular upgrade, but it just stopped working (perhaps during a suspend, but I'm not sure). I've found that rebooting to Windows actually fixed my problem before (but my Windows install is broken right now, so I can't see if it works again).
I played around with the hda analyzer tool a bit, but I didn't manage to fix it that way either. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/873990 Title: [3323A3G, Conexant CX20585, Speaker, Internal] No sound at all (headphones are fine) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/873990/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
