I just migrated from RPI3B+ to RPI4 with the new image for model 4.
Everything works using the player with my DAC+ pro card.
Unfortunately using the BT speaker function to connect the smartphone does not produce any sound.
The BT link seems to be established/connected, max2play is selected as the media output device, the transport of the music player advances but produces no sound.
Is this issue known in any form for the new max2play image?
Thanks – Udo
