I need help with my microphone, which is not working. It starts fine when I plug it in but after a few seconds of use (eg. recording or microphone monitoring in Audacity, speaking on Skype, or looking at the input bar bouncing in the Audio controls - before I uninstalled pulseaudio) it just stops working. I uninstalled pulseaudio because I had noticed that the mic resumed working after a killall pulseaudio, but it might have been a coincidence, since now I have uninstalled it and the problem remains.

I recently moved to Ubuntu 13.04 with a fresh install. I had had the same problem for a few weeks before (I had the 12 long term release version) but it was stopping to record after minutes, not seconds. The microphone is a Blue Yeti, which seems to work fine on Windows, as it did before in Ubuntu.

As a side note, the internal microphone has a lot of static noise, and gnome-alsamixer doesn't work, so I have to use alsamixer from the terminal.

I tried muting the right channel on the microphone (someone had written to try that in their blog) but didn't change anything. I tried installing qjacktl and ardour to see whether I could use the mic in some other software but I don't really understand how those work (the first somehow installed in German, which I don't speak that well) :-/

Here's the alsa-info report. I don't know much about audio drivers, so I don't know how to spot issues from there http://www.alsa-project.org/db/?f=b7...23320076b88bf7

Any help would be greatly appreciated.

The USB audio driver has been rather unstable recently, but also got many bug fixes. Try updating the kernel. (And your link is broken.) –  CL. Sep 1 '13 at 15:53
