A quick update on my recent experience.
I haven't loaded the dev version of A-O, because I'm a techno-wuss -- haha!
However, the June 5 security patch seemed to have stabilized BT significantly in my situation. I have a BT 4.0 USB dongle (with AUX output jack) for music streaming, and I let the phone connect to the car's head unit for phone. There is still some minor skipping -- occasional, very brief "tics" in the music playback (think milliseconds) -- but, nowhere near the extent of the problem before.
Some additional notes:
1. I switched to a BT 2.0 dongle, and the major skipping returned.
2. I switched the order of the connection sequence:
- car, then dongle = worse skipping
- dongle, then car = much less skipping (ie, minor tics)
So, music playback stabilization appears to be dependent on the connection sequence and BT version.
I hope that this information helps others who are waiting for the official release of A-O and that this June patch predicts the stability that A-O will bring.
