NanoPi neo air - Sound Delay

[JimmyPesto]

Hello,

 

as already described in this topic:
https://forum.armbian.com/topic/5619-nanopi-duo-sound-delay/
I have the same problem with delayed audio.
-> " if I run speaker-test -t wav, instead of the sound playing "front left" it just play the work left, the continues playing "front left" correctly."
When I run an audio-output-command two times, the audio is played well with the second command.
But the greater problem in my case is a loud cracking noise when audio stops. Is there anyway to prevent the shutdown of the amplifier?
I have to repeatingly start and stop audio files from nodejs.

Thanks for your help,

 

Jimmy
