It looks like it is going to be fixed upstream: https://bugzilla.kernel.org/show_bug.cgi?id=106961
...but from alsa-info attachment (here on launchpad), I can see that the fix may not work for your PC. The subsystem ID is slightly different. Mine is 0x103c1473, yours is 0x103c146f. Please try the proposed patch from bugzilla comments (link above). If it doesn't work, try the proposed patch with your value 0x103c146f and if this works, report it to the bugzilla.kernel.org so the upstream fix will work for you, too. ** Bug watch added: Linux Kernel Bug Tracker #106961 http://bugzilla.kernel.org/show_bug.cgi?id=106961 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1450027 Title: [HP ProBook 6550b, IDT 92HD75B3X5, Green Headphone Out, Front] Playback problem - audio works fine without headphones To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1450027/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
