Input Drops Through KVM Switch in c/linux@lemmy.ml
[–] Lars@infosec.pub 2 points 5 months ago

I've tried various ports on the motherboard and when directly connected to the same ports that the KVM switch was then there was no issue. I've been wanting to replace my kinda crappy board anyways so maybe the new one will fix it whenever I get around to it. I think I'm going to try to just use 3.5mm cables instead of USB and hope it works fine over the KVM switch. Just ordered a few.

I don't get any audio drops on my work laptop running Windows
Tried different KVM switches
and different ports
with all of the same devices connected but my speakers connected directly to my computer then I get no drops

The first one was powered by 5v off a dedicated usb charger. The new one uses an A/C adapter

Input Drops Through KVM Switch (infosec.pub)
 

For a long time now, I've had audio drops and sometimes even keyboard input drops through my KVM switches.
When a drop occurs, all audio across all applications drop at once. If there's a video playing then it'll pause briefly. In a game, I just miss a second of audio with no video stuttering.
When I connect my USB speakers directly to my motherboard then the issue does not occur; only through the KVM switch. I was using this decent switch I got off Amazon but just replaced it with one from Level 1 Techs and the issue remained. I've tried different ports on the switches and my board as well.
The issue also only occurs on my Linux computer. When I switch over to my work laptop running Windows I don't have the issue.
I'm not seeing anything in journalctl that seems related after swapping KVM switches. With the old switch I was seeing logs like below but no longer see that with the new switch.

Videos stuttering across all applications in c/linux@lemmy.ml

I had moved to a new house but my setup is the same as it was prior. I run updates regularly but I'm pretty sure the issue started after moving and before updating

Issue still occured. Didn't see my memory fluctuating either

I believe the only power tuning I had was cpupower. I just stopped it and will give it some time. Do you know a tool that'll graph out my memory frequency? My memory seems pretty stable at 4800 MHz but I'll watch it with "watch lshw -short -C memory"

It happens with only a single video or multiple. When there's multiple it happens to all at once

My cpupower profile was set to power save. I just switched it to performance and will give it some time

Videos stuttering across all applications (infosec.pub)
 

For a little over a month now, when playing videos on firefox, VLC, or any other application, I get infrequent stutters. This is with or without hardware accelleration. It's as if the video pauses briefly. If multiple videos are playing, even across different applications, each of them will be effected at the same time.
