Unable to choose Alsa output for bluetooth device

Help and Support
1

Upgrading my bluetooth device, I ran into an issue with no sound on my Vero4K+ out of the blue (had been working for months).

Unable to solve, I upgraded to Kodi19 via the buster-devel repository, and Kodi is operating properly.

Reading the new information for bluez-alsa, I believe the correct packages are installed.

osmc@osmc-sam:~$ dpkg -l | grep osmc | grep blue
ii  armv7-bluez-osmc                     5.43-6                              armhf        bluez for OSMC
ii  armv7-bluezalsa-osmc                 3.1.0-2                             armhf        Bluetooth audio streaming for OSMC

Using bluetoothctl, I’ve been able to pair and connect with my device no problem, and I’ve created and .asoundrc file for this device. However, in Kodi, there’s no option to output to my bluetooth device. When I enable debug logs and take a look, I see this:

The device “mybtdevice” is described in my .asoundrc file:

pcm.mybtdevice {
        type bluealsa
        device "10:D0:7A:B2:57:22"
        profile "a2dp"
        hint { show on description "BT-Headphones"}
}

I don’t understand why Kodi is unable to open the “mybtdevice”. Could I ask for some help?

I assume you rebooted and also you have the headset connected and enabled at the time you search it in Settings - System - Audio

3

Yes, and yes.

4

What is the info 10:D0:7A:B2:57:22 output from bluetoothctl ?

5

F me. I copied the wrong MAC address. Evidently this was something I didn’t re-check while trying to figure this out. PEBKAC. Thank you and sorry to waste your time.

P.S. I love my Vero
