I am guessing i could that and it would solve the problem, which would mean more cable work.
I wondered if there was a simpler problem in AMD catalyst software. I ask cos as soon as I turn off my computer monitor (2.1 systems attached), the sound automatically goes to the 7.1 system.
hope there is an easier solution. AMD catalyst people should think about this. as we select monitor, they should let us select sound device too.
