PA's autodiscover is a feature where when the computer's bluetooth connects to an audio device, PA will automatically connect to the device as well. Without autodiscover the user had to manually tell PA that the device was there. It's all behind the scenes stuff not related to preferences>sound

I suspect that bluetooth is reporting headphones that can do both A2DP and headset modes, and PA autodiscovery is trying to configure for both at once, leading to this issue. Through blueman we can connect only A2DP, so autodiscovery only sees A2DP and the confusion is bypassed. That's my theory, at least.

The realtime (rtkit) stuff may be a problem, but it's not causing this problem. In fact, the pulseaudio people I've talked to are baffled that these "skipping bytes" messages are showing up even with PA isn't supposed to be sending bytes in the first place.
