Workaround for crackling audio when music starts/stops - pato3 - 07-15-2021
When I start or stop playing any audio on my PBP, there will always be a crackling noise before and after, loud enough to make me worry about my external speaker system!
Finally I found a workaround to prevent this: I just continually play a sound file at zero volume in the background, that keeps the audio output active and the cracks are gone!
I use this command:
mpv --volume=0 --loop /path/to/audio/file.mp3
I thought some people might be interested in this workaround and use it as well.
Yes, this is far from a perfect solution, but for me it works so far and maybe one day an update will solve the issue :-)

Please, have a look at this forum post, which describes a somewhat better workaround, in the sense of possibly cosuming less CPU power. I've also created a kernel patch that makes it possible to turn off dynamic power management for the Pinebook Pro's audio codec, which eliminates the popping/crackling noises. It will be released as part of a patch series that will resolve the remaining audio issues on the PineBook Pro.
