Hello,
I've been struggeling with this issue for a couple of months now. So far I have been removing the audio crackle / popping post recording to the best of my current ability, but since this is a super time consuming workaround, I am now seeking help from ya'll because I have ran out of ideas and I lack the time to further troubleshoot this problem.
The issue: Recording gameplay for my channel on Youtube sometimes produces a little audio hiccup / glitch in sound that you can hear as a short crackling or popping sound every now and then. As far as I can tell it occures randomly, usually after recording 4-6 minutes of gameplay footage.
System specs:
Also tested on its smaller brother:
In both cases: No microphone connected to the pc, no other audio devices connected to the pc. Bluetooth dongle connected to the pc for mouse / keyboard combo and PS4 wireless controller.
Please note: I also tested on openSUSE Tumbleweed with both machines. The issue can be reproduced on both systems and on both Leap and Tumbleweed (the latter with a newer kernel 6+). The Optiplex 7050 is using a dedicated soundcard now, but initially it was using the onboard IntelHD audio chipset. After experiencing the sound issues, I decided to purchase a dedicated soundcard in order to rule out any conflicting issues with the onboard audio of the mainboard. Sadly, this didn't resolve the issue. The Optiplex 3040 computer is still running the onboard audio though. This happens in several games on Steam with Proton (Flatpak in both cases): Everquest 2, DC Universe Online, Anarchy Online and more. The sound glitches can not be heard during the live recording of these games, meaning that it is only noticable post record during video playback and inspection of the recorded material.
What I have tried thus far:
Plugins & filters used:
Untested as of this writing:
Fun fact: I have also noticed the exact same audio crackling and sound popping sounds on other popular gameplay videos on Youtube. This is merely one example - but there are more. Most ppl don't actually notice this at all, but I can hear it every single time it occures. Here it is at around minute 13:30 - 13:36: https://youtube.com/clip/Ugkx5CDcjfdXlQwdGrRhXNmkOtpjhzIepAfK?si=SC9ywS0ZSkU-iMBg
OBS global settings (screenshots) and last three OBS logs attached to this post. Example here after 13-15 seconds into the video. It can get louder / more quiet depending on the situation / scene.
Open for any form of feedback and suggestions! Thank you.
Cheers

What I have tried thus far:
- switch from 48khz to 41khz in obs audio settings
- disable desktop audio and other sound sources
- reduce recording quality from indistinguishable to high and medium via simple settings menu
- change audio codec from acc to opus in obs audio settings and tried both with 48/41khz
- create separate scene for sound source tapping into the dedicated xonar soundcard
- reduce rec gameplay audio in obs to -10db
- turn off video preview window in obs
- power profile in Gnome settings is set to maximum performance
- nvidia powermizer settings are set to maximum performance
- tried with and without gamemode %command% for the games that I want to record on Steam
- switch the default audio plugin within the operating system from Pulseaudio (default) to pulseaudio-on-pipewire
- switch from nvenc h264 to nvenc h265 recording
- set PULSE_LATENCY_MSEC=60 %command% for affected Steam games
- turn off PS4 controller in order to rule out audio issues since the PS4 controller has its own "speaker" that can be seen in openSUSE's Gnome audio settings (it's an audio source)
- set priority of the games and obs to very high in task manager
- pulseaudio-pipewire priority is already set to very high in task manager by default
Plugins & filters used:
- Linux Vulkan/OpenGL game capture (obs-vkcapture)
- added filter to "scenes" in obs: sharpening filter and color correction filter (now that I think of it, might be better to add the filters to the "game recording" source instead of applying it the the entire scene which includes the audio source
Untested as of this writing:
- I should try to record a different audio source like a video in VLC or on YT and compare the results with gameplay recordings. Does it happen when recording anything else outside of gaming gameplay?
- at least one person has suggested to switch over to a low latency Linux kernel, not sure if I want to do this on my computers since these are stable production machines and I rely on the default vanilla lts kernel coming from Suse
- haven't tested with native OBS yet (using Flatpak for now)
- haven't tested with native Steam and Proton yet (using Flatpak for now)
