Description Jiri Koten 2019-07-22 12:44:41 UTC
Description of problem:
Pulseaudio struggles to properly activate my bluetooth headset (MDR-1000X) after it connects. I have to use bluetoothctl cmd to reconnect the headset, after that the sound works fine.

When I try to set the card profile manually when the headset is paired, the pulseaudio crashed. 

Version-Release number of selected component (if applicable):
pulseaudio-11.1-22.el8
bluez-5.50-1.el8
kernel-4.18.0-118.el8

How reproducible:
most of the times

Steps to Reproduce:
1. Pair the MDR-1000X
2. $ pactl set-card-profile bluez_card.10_4F_A8_AE_2C_13 a2dp_sink
3.

Actual results:
Failure: Input/Output error
pulseaudio crashed

Expected results:
No crash, profile is activated

Additional info:
This is hw specific as I don't have such issue with other bluetooth headsets.
