I'm stuck in "No Stereo" land as well. It's really driving me nuts, to the point where I'm going to go back to A3 unless somebody has a fix for it.

Has anyone figured out exactly why it gets stuck...? Is it possible we could fix it with the config file, or through hijack, or...?

What sucks, is that I really love the stability of A5. It works much better for me. =/
