Hi,

I got a problem with bluez since 5.51 that was recently discussed in the 
thread https://marc.info/?l=linux-bluetooth&m=157081619423081&w=2: My 
headset auto-connects but is not registered as a2dp sink. Unfortunately, 
the proposed patch did not solve this issue for my setup.

I also could track down this regression to commit 477ecca (policy: Add 
logic to connect a Sink); applying it to 5.50 yields the connection 
issues. After that, I applied your patch in commit 52faac4 (audio: Fix 
cancelling disconnect timeout), but it did not change. I used only these 
two commits on top of version 5.50 to isolate the problem (it is the 
same with version 5.51 and 5.52) and gathered the logs of running 
`bluetoothd -dn` and `btmon -w` for the three setups:
* version 5.50 (patch-0),
* version 5.50 + 477ecca (patch-1), and
* version 5.50 + 477ecca + 52faac4 (patch-2).
For all three logs I powered the headset on to connect it, waited a few 
moments, and then powered off to disconnect. You can find them at

@Luiz Augusto von Dentz: Sorry if I sent you this mail multiple times, 
it probably got filtered from the mailing list as I attached the logs in 
previous attempts.

Please let me know if you need anything else. Thanks.
