Hi all,
For a couple of weeks now I'm trying to solve some weird behaviour of my setup. (rbpi4, RBPItouchscreen, HiFiBerryAMP2)
Sometimes everything works perfect, phone connects to bluetooth and Android Auto starts and I can control my audio.
But all the other times the audio slider is "stuck" on mute ,my guess is that the AMP2 is not recognised.
The aplay -l command shows "Subdevices: 1/1" when the AMP2 isn't working. It shows "Subdevices 0/1" when it works correctly.
I already added the following lines to the config.txt
[pi4]
max_framebuffers=2
force_eeprom_read=0
dtoverlay=hifiberry-dacplus
Does anyone have an idea what this could be?
My thanks in advance
Marten
