You got the gist...

There is no jackdbus on debian wheezy, just "jackd" or "jackd2".

That helps which means that debian wheezy has support for pulseaudio,
module-jackdbus-detect and jackd2 by default but there is still an error:

====
Failed to acquire device name : Audio0 error : Method "RequestRelease"
with signature "i" on interface "org.freedesktop.ReserveDevice1" doesn't
exist
Audio device hw:0 cannot be acquired...
====

What I find completely bizarre is that the top 5 hits on google for this
error have people recommending to disable pulseaudio or use an alternate
method to connect. It seems people have known about this issue for a while
and been ignoring it or waiting for someone else to figure it out.
