Error -16 means "EBUSY", or that some other application or daemon is trying to use the device, so PulseAudio can't open it. Could you check with this command:
sudo fuser -v /dev/snd/* to see if anything else is trying to grab the mic input? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1325282 Title: USB microphone inputs not detected by Pulseaudio on Kubuntu Trusty To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1325282/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
