Audio Sync issue with CachyOS

[HuntertronGames]

hello, ive found a issue with audio playback, overtime audio slowly delays from the video and i have 0 clue what causes this issue
ive tried changing sample-rate, audio monitoring devices, and even down to changing different audio input types including using plugins for native pipewire, i did a last ditch effort and tried using jack and the audio still delays itself

OBS meters shows its still in sync compared to what im actually hearing on the output monitor, again i don't know what causes this as it seems to be random as i did a all night test of it idling and it was still in sync and then 20-45 minutes of gameplay then it delays, it throws off my momentum flow on my monitor mirror when playing rhythm games to a audience

ive even tried using a aux jack hooked into my monitor so it captured the pass through audio into one of my microphone jack ports on my PC, so its not a USB capture issue

it seems to reset itself when rebooting OBS as well btw, but it shortly de syncs after, had it happened on stream once as well

for now a workaround i have done is not to use OBS monitoring and manually route the mic to the sink output i have (jamesDSP), which allows me to hear my caputre audio and it will always be sync as there is nothing external causing this same problem, the thing tho that this makes it hard to tell if OBS is actually desyncing with the stream, so i would still like to hear some ideas to resolve the issue with OBS monitoring

Hi I have not noticed any out of sync problem with my setup - but possible I need to test it more but I am not happy with the out of the box repositiry solution - its missing the browser-source and does not detect VLC player but I did install NDI-sdk with succes using:
yay -G ndi-sdk
cd ndi-sdk
updpkgsums
makepkg -si

Else I am happy that it looks like I can use my old lenovo laptop V130-15IKB 81HN (Lenovo V1) with I5-7200U but I am very new to CachyOS so have alot to lean because flatpak install of obs-studio did have browser-source but NDI was not detected. With 3 mevo cams in NDI full 1080 the load is around 50% on this computer using HD630 gpu.

I find it very strange that browser-source is missing

Are you using the obs-studio from the binary repository ?

im using the git version using the AUR using yay, but i should add that i have the same issue using the browser version, which yes is in the binary repository for CachyOS under the package obs-studio-browser, as far as im aware obs-studio-browser is just stable but adds back in browser source

i don't use the flatpak version of OBS because i lose access to specific AMD encoders i take advantage of using my RX7600 (mainly AV1)

the sync issue im having doesn't happen immediately, its something that happens either at random or over time, im audio sensitive when it comes to latency and something happening by a hair causes me to notice and throws things off for me
