Hello Manjaro,
I have a bluetooth headphones and I think I am using default bluetooth & pipewire configuration that comes with Manjaro Gnome.
The issue is:
I am having audio glitches while using bluetooth headphones.
Audio is getting faster and slower just a little bit. It is so small that I usually can’t recognize it while watching a movie. It is almost an invisible/inaudible glitch.
But while listening some music, it becomes audible. I can hear it from microtonal pitch changes during a song. I do love jazz, but this is too jazzy to listen 
I tried different headsets, result is the same.
I am using 5GHz WiFi connection, so bluetooth-wifi signal interference is unlikely. Plus, I am having the same issue while WiFi is off.
I wan’t to solve this issue because right now it is almost impossible to listen some music using my computer.
