Title:
PC streams music over low-quality HFP/SCO connection, instead of
A2DP/AVDTP
Status in pulseaudio package in Ubuntu:
New
Bug description:
This issue was first discovered when I got this headset 2 years back:
https://www.amazon.co.uk/gp/product/B01C2QCPYI.
STEPS
* Enable Bluetooth on the PC
* Have music or some video playing on the PC
* Power on the (already-paired) headset. It automatically connects to the PC.
EXPECTED RESULT
The PC's audio should now be streamed to the headset, over high-quality A2DP
ACTUAL RESULT
The PC's audio gets streamed over the low-quality HFP/SCO connection instead.
Stopping and resuming the stream changes nothing. I have to manually
open Blueman and right-click on the device and select "High-quality
A2DP profile", for it to switch to the expected high-quality A2DP
transport.
HCI snoop logs and verbose bluetoothd-syslogs taken in both headset-
initiated and PC-initiated connections are attached.
