I just purchased a pair of Sony WH-1000XM4s and have been impressed with the audio playback (music, calls).

However after spending an hour of configuration on Kubuntu 20.04, I cannot find any way of using the headphones with HFS mode and having high quality playback and recording.

Therefore as a current workaround I am using a separate laptop microphone as audio input and the bluetooth headset for audio output.

Is this a limitation of bluetooth, the distro, linux drivers?

Is there no way to hack this to have good quality?

Kubuntu Version: 20.04

Bluez Version: 5.53-0ubuntu3.3

Pulseaudio Version: 13.99.1

Pulse Audio Profile: A2DP Sink: LDAC

I have setup Ubuntu 20.04 in Dual boot with Windows 10.

On Windows 10 @ 3840 x 2160 (16:9) resolution I do not have any issues with video, smooth scrolling, IDE, games.

However on Ubuntu @ 3840 x 2160 (16:9) resolution, I get stuttering low FPS for video, jaggy/rough scrolling.

When I set it to 2048 x 1152 (16:9) resolution it is way smoother and no issues.

My hardware info is the following:

Intel(R) Core(TM) i5-4690K CPU @ 3.50GHz
Palit GeForce RTX 2070 8Gb
16Gb DDR3 2400mhz Corsair Vengeance RAM
LG 27inch 4K Monitor

These are the following things I've tried:

• Swapped HDMI to Displayport from GPU to Monitor
• Tried the prorietary Nvidia drivers (version 440), X.org drivers
• Restarting Gnome
• Updating the latest drivers and patches from Ubuntu

I am happy to use the monitor at a lower resolution but I am curious as to what the bottleneck is here?

Is there any fixes?
