Hi everyone

I am using Ubuntu 9.04 on a Sony Vaio and I have problems with the mixer, they started some time ago but I cannot link them to any specific action I took

the speakers are working but when I plug the woofer in (or headphones) they keep on working (and I have found no way to make the switch) and from the woofers only a "secondary" sound comes out, that is if I put the volume up, it's the computer loudspeakers and not the external devices that will play louder

any help?
