Missing wide band speech support (Bluetooth A2DP codecs). -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to pulseaudio in Ubuntu. https://bugs.launchpad.net/bugs/1941977 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.
