Track is not playable error


I am recently having trouble playing tracks on my raspberry pi 3. I had it setup with a bluetooth speaker and was working well until all of a sudden it stopped playing. I ran a service status and have the following error:

     mopidy.service - Mopidy music server

any ideas?

thank you.

I think I resolved this issue. Something weird happened. I had the bluetooth speaker set to alsasink device=btspeaker but defined the speaker in asound.conf as follows:

pcm.btspeaker {
type plug
slave.pcm {
    type bluealsa
device "XX:XX:XX:XX:XX:XX"
profile "a2dp"
hint {
show on
description "Bluetooth Speaker"

ctl.!default {
type bluealsa

The weird part is the device MAC had changed and that’s why it wasn’t able to load the music. Anybody ever seen the MAC address of a bluetooth device change?

Looks like you hit
