first of all Hi to every one.
I have been using Linux for quite some time now and I desided to try BackTrack 4.
So i installed it on my HDD and all is fine it nice and fast os but the only problem that i have and cant fix is the sound. I have been reading all over you`r forum and googled it to but cant fix it... it seems all ok but no sound at all.
In alsamixer is all ok
