I’ve built my V3 kit in April this year and everything worked fine and as expected (considering a Raspi 3) including Pianoteq Stage and PD patches.
The OS version I used until now was “2020-04-30-zynthianos-buster-lite-1.0.0”. I recently decided to catch-up with an update to the current “latest-stable” (2020-09-06) release. After flashing the SD-card I enabled WiFi and chose the “Kit V3 Pro” hardware and audio parameters.
From now on the sounds of every synth engine produce erratic but somewhat repeating digital crackling sounds. There are no xrun or power warnings visible and checking logs and CPU load or temperature doesn’t hint any problems. The crackling can be forced even more by rotating the encoders or fiddeling on the touch screen. The crackles stop after the sound from e.g. ZynAddSubFX is finished playing (release end, no more reverb tail).
Could there be any problems I produced building my Kit 3 hardware, that are getting obvious now?
Or is this a bug?
Does anyone else experience problems like this?
