Hi, I've been running ubuntu 12.04 for a while now but I've not managed to fix this glitch.

Skype works fine but the sound quality from my mic is poor (although audible) on the other end. I can hear fine my end.
It's not the hardware as I've tried plugging in an aux headset and no change.

Is it possible that my mic drivers are slightly wrong? I'm not sure what else to try.

The computer is a Fujitsu Siemens ESPRIMO MOBILE V5515.

Any help would be really great as I'm going abroad next week for a while and I want to be able to keep in touch!

Thanks!
