[PROBLEM] Can't connect SPDIF/BT transmitter to moOde

[romain]

The result of step 1 suggests that bluealsa-aplay has not been started by Bluetooth or has crashed. It's the player that Bluetooth launches when a client connection is successfully established and is what moOde looks for to trigger displaying the BT overlay screen.

After step 1 you can try:
bluealsa-aplay -l or --help for more options.

Also if it's not running (pgrep bluealsa-aplay = blank) you can try to run it manually using the MAC address of the CM150 to see if it prints any errors.
sudo systemctl start bluealsa-aplay@MAC_ADDR
systemctl status ...

Hello,

Code:

bluealsa-aplay -l

lists CM150 as a playback BT device ; it returns device name UG-SPDIF-TX as well as MAC address and type audio-card.

However, unless I connect another BT source to moOde, I have to manually start the bluealsa-aplay@MAC_ADDR.service to get it to work and see the BT overlay screen with the device name displayed.

I also have to manually stop the bluealsa-aplay@MAC_ADDR.service otherwise BT overlay remains displayed without device name when the CM150 is powered off and moOde doesn't fallback to MPD.

As for latency, with a length of 20 ms set for output buffer, sound and picture are almost perfectly synchronised without noticeable dropouts

So, the problem now is that the bluealsa-aplay service is not starting nor stopping automatically with the CM150.
