Struggling to get any sound output from the DAC Shim Line Out. /boot/config.txt edited: dtparam=spi=on dtoverlay=hifiberry-dac gpio=25=op,dh snd\_rpi\_hifiberry\_dac shows selected when right clicking speaker icon on desktop aplay -l shows card 1: sndrpihifiberry [snd\_rpi\_hifiberry\_dac], device 0: HifiBerry DAC HiFi pcm5102a-hifi-0 [HifiBerry DAC HiFi pcm5102a-hifi-0] cat /proc/asound/cards shows 1 [sndrpihifiberry]: RPi-simple - snd\_rpi\_hifiberry\_dac snd\_rpi\_hifiberry\_dac I can get audio via rpi jack but not at the DAC shim. I have tried #dtparam=audio=off but still no output but also gives me an error “Couldn’t reserve audio samples” on my chosen player (fruitbox) Have I got a broken shim ? ---

What do you have connected to the Line Out? If it’s speakers, they need to be amplified speakers. ---

Ok, it’s not that then. Clean install of Pi OS? Any tinkering etc done on that Pi previous to this? ---

Just tried a clean install of Volumio3, only because its a quick and reliable install (I have 2 pi’s running it) - still no sound ---

Another clean install (Raspian Buster) and installed Mopidy per the Pimorini instructions. DAC is recognised and selected. Mopidy has found and scanned the music files. Still no audio via the Iris UI. ---

Did you use the same micro-SD on your old Pi2 (i.e. running the clean install Buster)? The reason I am asking is that more recent versions of PiOS use pulse-audio instead of pure ALSA, maybe this is part of the problem. And have you tried running pavucontrol?
