Hmm after a reboot, the problem appears to have gone away. My selected h/w profile is "Analogue Stereo Output + Analogue Mono Input" (which has not changed).
There are a couple of extra odd things going on here: 1) if I change the h/w profile for the headset to "Analogue Stereo Output" and switch to the Output tab, the selected device is "Internal Audio Analogue Stereo" (!), and yet the sound is still coming out of my headset! And no sound is emitted by my internal speakers or via the headphone socket. Additionally, I now have no control over the volume: changing the sliders does nothing. 2) Selecting "Analogue Mono Output" for the headset device degrades the sound quality significantly (I can hear a lot of crackling mixed in with the sound). -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in Ubuntu. https://bugs.launchpad.net/bugs/917165 Title: gnome-control-center does not allow selection of USB headset for input or output To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gnome-control-center/+bug/917165/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
