Hi
There is something weird on the sound output on RPi when setting audiooutput.processquality is set to GPU accelerated (Settings->Audio->Resample Quality).
I tried it in a Pi2 and Pi3, and the sound output has this weird out of phase noise, it sounds like there’s something varying the pitch, similar to the effect of bending strings up and down on a guitar. It’s hardly noticeable with voice, but it’s noticeable with background music or even slower music. I can try to record some audio to “illustrate” this better.
When set to High it gets back to regular.
Is this something you’ve come across as well ?
Maybe @popcornmix has some insights about this.
Regards,
