Plugging in the headphones does not mute the laptops speakers, music does play out of the headphones but also continues to play out of the speakers as well. alsamixer's 'auto-mute mode' is already enabled.

when I look at the sound settings in, 'output devices' it only has 1 item in the list 'Speakers Built-in Audio'. Yet when looking at 'PulseAudio Volume Control' under 'output devices' the 'Port' drop-down list has 2 options 'speakers' & 'headphones'. Selecting 'headphones' from that list does mute the speakers.

Specs:

  • Ubuntu 12.10
  • Asus K55A.404

aplay -l output:

  • Thanks. While I had tested all these solutions, none of them worked for me. It turned out to be a hardware based issue.
