[Bug 1487889] Re: After disconnnecting from car bluetooth, audio is still routed to bluetooth


Using the new bluetooth stack I have not seen this issue again on arale

fastboot flash boot boot-arale-newer-bt-stack-1.img
fastboot reboot

Now verify that the kernel is really what it should be:

$ sudo dmesg | grep Bluetooth
[    0.198808] Bluetooth: Core ver 2.20
[    0.198863] Bluetooth: HCI device and connection manager initialized
[    0.198888] Bluetooth: HCI socket layer initialized
[    0.198910] Bluetooth: L2CAP socket layer initialized
[    0.198965] Bluetooth: SCO socket layer initialized
[    0.867176] Bluetooth: RFCOMM TTY layer initialized
[    0.867213] Bluetooth: RFCOMM socket layer initialized
[    0.867248] Bluetooth: RFCOMM ver 1.11
[    0.867277] Bluetooth: BNEP (Ethernet Emulation) ver 1.3
[    0.867293] Bluetooth: BNEP filters: protocol multicast
[    0.867319] Bluetooth: BNEP socket layer initialized
[    0.867336] Bluetooth: HIDP (Human Interface Emulation) ver 1.2
[    0.867361] Bluetooth: HIDP socket layer initialized

and that the hci0 device is up

$ hciconfig hci0
hci0:   Type: BR/EDR  Bus: UART
        BD Address: 38:BC:1A:1F:7E:96  ACL MTU: 1021:8  SCO MTU: 244:4
        RX bytes:716 acl:0 sco:0 events:43 errors:0
        TX bytes:1475 acl:0 sco:0 commands:43 errors:0

Then continue to use your device as normal.

  After disconnnecting from car bluetooth, audio is still routed to

Bug description:
  MX4 r96

  This has been happening fro a few weeks
  Phone automatically connects to the car, you don't have to make or receive a call
  Leave the car and disconnect
  Place a call
  The audio starts out using the phone as expected, after a few seconds the audio switches to bluetooth
  You can manually change the audio in the UI
  This happens until you reboot
