Static noise while sound is active (bluetooth)
I recently used pulseaudio again for a while and decided to check out pipewire again, with new bluetooth headphones.
I noticed that they had some sort of static noise, but it was not so much noticed as with pipewire.
Basically this is a static background noise that occurs every time when playback is happening. Sounds like a square wave sound, and pipewire (compared to pulseaudio) has much higher frequency of that square wave sound.
Best sound quality was actually on Android (in my case LineageOS 17.1). It has much lower frequency and volume of this static noise compared to both pulseaudio and pipewire on PC.
I can assume this depends on bitrate used by device, but i'm not so sure.
I'm using A2DP SBC codec, not HSP/HSF
What i can use to tune this static noise and possibly lower it's volume/frequency?
