I just recently got myself a pi-top with an already built in rpi4.
I now realized, that the built in speaker constantly emits a static noise.
Lowering the volume doesn’t change the static. It is quite, but can clearly be heared when but near the ears.
At first I even thought the pi-top4 has 2 built in fans…
Is this normal behaviour? If yes, are there any configuration options (maybe in config.txt) that would eliminate this static noise?
On the net I found some posts about disable_dithering or audio_pwm_mode=2, but I didn’t want to experiment stuff before aksing here.
Hope someone can help.
