12.04 - Input device of combined audio jack not recognized anymore

  • JD3

    I'm running Ubuntu 12.04 on a Lenovo T420.

    This laptop has a combined audio jack for sound in/output. Connecting my headset via a splitter adapter to the laptop results in the sound being played correctly on my headset.

    But pulseaudio does not recognize the microphone as input device anymore.

    About six months ago my workflow included using the audio jack for sound input and at that time everything worked fine. I cannot say when exactly this change happened.

    alsa - No audio duplex option in sound options in 12.04 on Vaio VPCS131FD
  • Jennifer Yu

    I recently did a clean install of Ubuntu 12.04 on a Sony Vaio VPCS131FD. Yet the audio duplex option is missing on my sound option and the computer no longer does jack detection. And I think the sound is a bit weaker now but I am not sure. This computer worked under 11.10.
