I have sound but can't see any audio-input (mic) device in settings. The mic works, I have tested using gnome-alsamixer by redirecting the mic to output.

But when I try the sound recorder it says "your audio capture settings are incorrect". Also Google-talk plugin says I have mic problems.

**** List of CAPTURE Hardware Devices ****
card 0: NVidia [HDA NVidia], device 0: ALC883 Analog [ALC883 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: NVidia [HDA NVidia], device 2: ALC883 Alt Analog [ALC883 Alt Analog]

  1. The rear mic is detected, and works, the problem remains with the front-mic.
  2. I also use front and back plugs at the same time, and it seems to be a detection problem, the front speakers work (at the same time and channel with rear), just the front-mic doesn't. Can the mic be set to be always on?

    Try pavucontrol – Aiphee Feb 27 '14 at 15:33

I would try 2 things:

  1. Unplugging and plugging the microphone.
  2. try restarting pulseaudio with killall pulseaudio in terminal
  • just tried 1. & 2. , no change with both : sound-recorder still same error and the "Record sound from" listing remains empty – Stefan Rogin Jan 18 '14 at 13:32
  • The firs gave me and idea, so I plugged it in the rear and it works. Now how do I make it detect the front-mic, or make it skip the autodetect? – Stefan Rogin Jan 18 '14 at 13:36
  • I got no idea why it wouldn't detect the front plug. Mine detects it fine. :( – Dan Johansen Jan 18 '14 at 13:49
  • updated question. – Stefan Rogin Jan 19 '14 at 11:25

I had the same issue. I used pavucontrol to change the input device to the front mic instead of the rear mic.

  • so you can't have both set at the same time ? – Stefan Rogin Sep 17 '14 at 20:09
  • or you just manually switch each time you plug a mic ? – Stefan Rogin Sep 17 '14 at 20:10
  • The GUI in pavucontrol does not allow selecting both at the same time. Indeed I manually switch each time. – lacton Sep 18 '14 at 8:51
