I’m not sure what it might be or when it started or if it was always here.
I’ve been using Manjaro for 6 months now and i noticed recently that my CPU usage is really high when i am watching videos or listening to Youtube Music.
Example :
watching a 4k video with audio i get constant 85-90% CPU usage
watching the same video without audio it goes down to 40-50% CPU usage
This gets annoying when i am trying to listen to music while coding as i have multiple web windows, apps, processes open.
Also Videos and Audio work perfectly with the same device on windows.
Specs:
Audio: Device-1: Intel CM238 HD Audio vendor: ASUSTeK driver: snd_hda_intel v: kernel bus-ID: 00:1f.3
CPU : i7-7700HQ
GPU : GTX 1050 TI
RAM : 8GB
I haven’t made any configuration changes either in firefox or chrome, the problem occurrs in both browsers. I’m not sure if i have downloaded any new packages that use audio, except maybe for kernel updates?
One of the 19 devices might be a match to the onboard audio device on your system. I cannot be more specific due to incomplete data
I would have expected that using only one sound server might reduce the excessive CPU load
The only other thing I can think of is to try using a later kernel version than v5.5
So I suggest you use this command to install kernel v5.10
sudo mhwd-kernel -i linux510
and reboot system to load new kernel
If you still have audio or CPU load issues with kernel v5.10, please post response to this command to show more information about the onboard audio device
Found the problem, it actually was plasmashell audio widget causing the high cpu usage.
The widget animates the output bar based on sound. Which for some reason causes high cpu usage.
