    I tested both Digital Output (S/PDIF) and the speakers in the sound settings but can hear nothing. I also tried

    It depends of the system. Begin with this, and if it is not solved, I tried this and it worked for me.

    Step 1: Open a Terminal (CTRL + ALT + T) and start alsamixer.

    Step 2: Go to the Auto-Mute option and press down to disable this option.

    (In my notebook (Sony Vaio SVS15127PXB), alsamixer needed to be scrolled to the right to show the Auto-Mute option.)

    12.10 Poor quality sound when using headphones
  • changeableface

    Recently upgraded to 12.10 - I know it's not released yet. Having issues with sound when using headphones plugged into the front ports. Something that doesn't happen when booting to windows - so fairly confident it's an Ubuntu issue.

    When listening to any sound, music, video etc the sound levels jump up and down and click. If I open "sound" from the settings menu when playing videos or music and viewing the "output" tab I can see "headphone - built-in audio disappear and reappear (very quickly) so I'm guessing the system is jumping back to the "analogue output" and back again which is why the sound volume changes and clicks.

    Worth noting I never used my headphones when 12.04 was installed so not sure if it's this OS or Ubuntu hates my hardware generally.

    Anyone seen this before? any advice?

    Sound is built in to motherboard. I have the Gigabyte GA-X58A-UD5.
