You are correct.  I do a bunch of my R&D on a VM because the hardware is so much faster than the pi.. and I try not to compile over and over on the pi.

So, I went through the set up this on my pi, to verify functionality.

It really does work much better. As far as stability and functionality I would say it works like it should.

After the first call, the audio is broken and distorted.  the A2DP profile still plays perfectly though.

I don't know which layer this is happening it.  I restarted pulse, ofono, and bluetoothd methodically testing after each and could not improve it.

So, that could at any layer.

Thanks for your help.  I've been struggling with this setup for a few weeks, trying to get it all to work.
