Solution NicoD Posted November 10, 2023 Solution Share Posted November 10, 2023 I know this is the same on other Rockchip devices. Not sure what the cause is. Might be interference. I use usb audio adapter or hdmi-audio on all my boards. Never the on-board audio jack because it was a problem long ago with other boards. Even RPi used to have terrible sound on audio jack if I remember well. 0 Quote Link to comment Share on other sites More sharing options...

quackmore Posted November 13, 2023 Author Share Posted November 13, 2023 thank you I ordered a HMDI to VGA adapter that has an audio jack output too but I'll keep your suggestion as a backup solution 0 Quote Link to comment Share on other sites More sharing options...
