I now attach the log file, as requested. The log corresponds to the following sequence of events
1) Play sound (no headphones plugged) 2) Plug headphones (not working) 3) Go to Soundpreferences->Output->Analog Speakers (now headphones working) 4) Unplug Headphones (speakers now normally working) 5) Plug Headphones again (nothing changed in sound preferences, so not working) 6) Unplug Headphones (again speakers working fine) 7) Stop logging. ** Attachment added: "pulseverbose.log" https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/874880/+attachment/2553103/+files/pulseverbose.log -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/874880 Title: Ubuntu 11.10 Headphone-To-Speaker Switching for Intel HDA To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/874880/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
