ac=hwac3 causes a buzzing sound on my setup :(
Basically what setup I'm looking for is 2channel mp3 gets piped to all
speakers and anything ac3 will get do 5.1, currently I have the 5.1
part working, but everything thats 2 channel only gets played to the
front speakers.
Is there any way to do this?
