Hi folks,

 

I have a samll problem with my NanoPi M4. I connected an amplifier with some speakers to the 3.5mm Audio Jack. When I try to play something with mpc or ffplay, I only here some (maybe white) noise on the speakers. Stopping the playback, and the speakers are quiet again.

Output of aplay -l:

Has anybody any idea, where I should have a look next?

Maybe this may help.

@sven222 Could you please give a bit more info. What os are you running? What kernel? The output of sudo armbianmonitor -u

Or google in the forum for "alsa mixer m4"
