Yes, muting in Sound Settings does mute (MM) in alsamixer. The USB device in Sound Settings seems to map to my internal speakers instead of the USB ArtDio NB-005B speakers . No matter which audio device I choose, my internal speakers remain playing the audio (and the USB ArtDio NB- 005B speakers never play, while there power light is indeed on). Muting my USB device (in Ubuntu Sound Settings) mutes my internal speakers in alsamixer but so does muting my internal speaker device (in Ubuntu Sound Settings). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1074783 Title: ArtDio NB-005B USB Speakers Stopped Working in Ubuntu 12.10 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1074783/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
