Jane Silber (silbs) wrote : sound only from built-in speakers, not headpones

Sounds only comes from built-in speakers, whether or not headphones are plugged in. This started happening on Karmic after I ran a Mumble session, and has continued into a Lucid upgrade. Other tidbits:

- the same behaviour happens if I plug headphones directly into laptop, or into the jacks on the docking station, or if I use the little USB-jack thing that came with the headphones

- the headphones work fine on other computers

- The mic in the headphones still seems to work, even when sound will only come from the built-in speakers

- I've checked sound preferences, can't find anything that is muted
