Public bug reported:
I'm using Bose QC35 headset and Dell XPS 9570 laptop. It was working
perfectly on Cosmic, after upgrade to Disco when headsed is switched to
HSP/HFP mode in pavucontrol I'm getting bursts of following messages in
dmesg:
Apr 24 23:27:28 daffy kernel: [53021.123542] Bluetooth: hci0: SCO packet for
unknown connection handle 65534
Apr 24 23:27:28 daffy kernel: [53021.123551] Bluetooth: hci0: SCO packet for
unknown connection handle 0
Apr 24 23:27:28 daffy kernel: [53021.143555] Bluetooth: hci0: SCO packet for
unknown connection handle 63744
Apr 24 23:27:28 daffy kernel: [53021.153575] Bluetooth: hci0: SCO packet for
unknown connection handle 1
Apr 24 23:27:28 daffy kernel: [53021.173563] Bluetooth: hci0: SCO packet for
unknown connection handle 63744
Then, after at most a few minutes, after one of bursts like above,
pulseaudio reports:
Apr 24 23:27:28 daffy pulseaudio[2733]: W: [bluetooth] module-
bluez5-device.c: SCO packet received of unaligned size: 5 (the size
differs between runs)
And the headset is getting disconnected from pulseaudio - it's still
connected via Bluetooth, but it's status in pavucontrol switches to
'Disabled'.
