Public bug reported:
Hello!
After some update (probably linux kernel) in autumn I noticed that bluetooth
audio started to lag heavily and shutter when Wifi is working hard, i.e. when
there is active download process (open web site, download file, etc). Looks
like bluetooth is not prioritized over wifi causing delays in bluetooth frames.
Usually the most popular question is what frequency is used by Wifi. I use only
5 GHz for wifi.
