hifibarry Dac + pro selected

also ssh to edit config txt and remove “slave” from dtoverlay=hifiberry-dacplus as sugested

getting the red error “faild to oopen alsa”

what am i doing wrong ? thanks

The moodaudio protodac? i do not have pi400 but you can
try Generic I2S or hifiberry DAC or R-PI dac

if that doesn’t help, you can try an older version.

for example. if that version work, an update to actual version should work and is also recommend.

Hi , thank you for your reply , yes the “moodaudio protodac”

i have try all 3 Generic I2S or hifiberry DAC or R-PI , and i can now play it without the alsa error but no sound coming out of the dac rca

befor i do a downgarde any other suggestions ?
