Firstly, thanks for the response, Colin!
I will have to double check when I get home, but I'm near 100% sure
that I have not set the default alsa device to route through pulse.. I
will double check though, because I'm not 100% sure what build-root
has done. :D

Forthcoming when I get home..

Phew.. thought I might be crazy!

I honestly have no clue what's supported, but this gives me hope! I
will look into it..

I'm not sure I understand this.. I mean, I understand what you're
talking about, I'm just not sure I know how to look at this. Is there
an example that you can give me?

That's what I figured, I'm gonna remove them again :D

Ok cool.. I'm going to go back to the stock PA for now then. I don't
want any more variables than I need to troubleshoot this.

Thanks again Colin.. I really appreciate it!
