I now believe that this is actually a bug at least involving pulseaudio, but may also be caused by Sound Prefernces, or even other parts.
The advice given in Bug #437192 in comment #60 by mikedev does work but shows some extra oddities, which I'll describe. I installed pavucontrol (pvc) and opened it side-by side with Sound Preferences (SP), clicking on the input tab in both windows. The two individual sliders in pvc for Front Left and Front Right move together when I move the (single) input volume slider in SP. Even when thus all three sliders are maximized, the Input Level indicators in both programs remain at silence. However, when I move either one of the paired sliders in the pvc, the Input Level in both immediately shows activity. I can now - internal microphone only, no external one plugged in - do a Skype test call successfully and also record with sound recorder. (Voice quality, though, is poor). When I now move the single slider in SP, the double sliders of pvc jump to identical setting, and the input level in both pvc and SP stay at silence. No sound can be recorded in Sound Recorder or Skype. -- [ubuntu karmic] internal microphone is not recognized in netbook https://bugs.launchpad.net/bugs/525990 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
