I've recently tried Linux, and love it. I'm hoping to make the full switch from Windows but due to one niggly thing I can't just yet. I currently have a 4 speaker set up (subwoofer, left, right, centre). No sound will come out my centre speaker. I'm unable to find any sound settings within Ubuntu to play with, and I can't find Linux drivers for my Asus M2NPV-VM board with on board sound.

Any ideas?

Thanks,
