after trying & failing for...4 hours...I need to ask you. I am going crazy with this issue and I can not fix this by myself.
All I want is to get my subwoofer in my Acer Aspire 7738G working. Well, last year I got that working until i removed Linux again, but don't ask me how I managed that.
I tried every possible solution I found through Google, but none of them worked. So please haaalp!
only plays sound from front-right and front-left
