Public bug reported:
Recently upgraded to 12.10. 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. Booted from
live cd (usb) to 12.04 and there wasnt any issue.
Anyone seen this before? any advice?
Sound is built in to motherboard. I have the Gigabyte GA-X58A-UD5.
