I had this problem with Manjaro on my macbookpro 2016.

Now I am having same problem with Fedora 35 on PC. I googled it and some forums says it causes due to 2.4 GHz issues with Wifi.But now I am using ether-net cable and it is still happening.

It doesn’t matter what I’m playing it offline or online source. Audio becomes lag when I am downloading files.

I am using also using MX Master2s.

  • Sony WH1000XM3 ( LDAC )

  • Orico Bluetooth 5.0 Adapter on PC

Welcome to ask.:fedora:edora @sherrinford

Could you please give us more info’s as :

inxi -Fzx in terminal and post the output as </> Preformatted text here.

Have also a look to pw-top to see what goes on when you open something with audio/video.

Just check, if you use USB3 to power your Bluetooth. If you need an extension cable for USB look for a good one and keep it short. Preferably use USB3 on backside …

Did you try without the mouse once, to see if the problem still exists.

I also changed Bluetooth Adapter to USB 3.2 port on the back of the PC and not using mouse at the same time.
When I am screen-recording during speedtest , audio stuttering happened.
But the screen-record video doesn’t happen audio stuttering.

Since you’re using snd_hda_intel driver, you could check:

cat /sys/module/snd_hda_intel/parameters/power_save

and

cat /sys/module/snd_hda_intel/parameters/power_save_controller

If it said 1 and Y respectively, you could disable it with modprobe by createng file inside /etc/modprobe.d/mycustom.conf and add below config:

options snd_hda_intel power_save=0
options snd_hda_intel power_save_controller=N

Reboot your system and test it.

Found other possible way. Open Gnome System Monitor, if you’re using Gnome or other equivalent, there find wireplumber right click, select Change Priority, change it from normal to Very High. Usually anything related sound process will on very high priority and I don’t know why wireplumber set to normal, only pipewire set to very high by default.

Sorry for late reply.
Thanks I solved using this method.
