I have this issue too, on 12.04. It is impossible to switch between Headphones and Built-in laptop speakers, they both work together. I did not have this issue on 10.04.
Panasonic Toughbook CF-y7. Running Gnome fallback/classic, though it is the same problem on Unity. In the sound settings I've tried switching between Analogue Stereo Duplex and the other options but that doesn't help. ** Attachment added: "cat of asound files" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/995684/+attachment/3189260/+files/asound_contents.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/995684 Title: Switching problem between headphone speaker and microphone to laptop built in speakers and front mic To manage notifications about this bug go to: https://bugs.launchpad.net/alsa-driver/+bug/995684/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
