Hello, I have three Raspberry PI 3b+ running M2P version Version 2.56.
On one of these that has Hifiberry Digi+ with Tosslink (optical out) I cannot get any sound over Bluetooth. Phone connected, BT plugin installed and running, Stream directly to soundcard enabled, soundcard selected, everything seems OK, Tidal playing song, but no sound. Squeeze lite and all other things work OK. I have tried different BT devices, no luck, tried enabling-disabling „Enable I2S-MMAP“, …
On the other two RPI with Hifiberry AMP+ everything works fine, including BT streaming.
Any clue what else to try? Isn’t somewhere mixer that would put the input to 0 or something? Thank you for any ideas.

Hi Kops,

You somehow have two Bluealsa instances running, which could possibly interfere. Maybe try uninstalling Bluetooth on the device (inside the Bluetooth plugin), then update your Max2Play version (under Settings/Reboot) and then reinstall Bluetooth. Try connecting only the smartphone, set the audio player to the correct output and test the direct stream to the sound card again.

You could otherwise check the volume by accessing the Pi via SSH (or with our remote control plugin) and typing alsamixer. There you can set the output via F6.

Hi Mario,
thank you for detailed steps. I did follow these but it ended up the same. The fact of having two Bluealsa happens once I install BT plugin and then (the second) when I enable the BT speaker below in the plugin.
However, I managed to make it work, however it is a bit weird. When I stop Squeezelite service, the BT starts playing flawlessly. It is interesting, because on the other RPI I do not have to unload Squeezelite to be able to play over Bluetooth.

Thank you anyway for your help.
