Weird Audio Problem in Live stream

[Nashit]

I live stream once in a week on my YouTube channel I am doing this for past 3 years or so
But from last 3 months I am encountering an issue with the audio in my Livestream

"Audio Slowly Dies (fades out) at any point in live stream and after that there will be no audio untill I notice it (which is mostly Missed by me)and unplug and then plug the mic again"

What I have done to fix this issue is I changed my mic (3.5mm jack)
And notice the results
From Mic 1 after 14 min audio dies (which is brand new)
I changed again mic
Fro mic 2 audio dies after 19 min or so
I changed again the mic
For mic 3 audio dies after 29 min

So there is no specific pattern in that and issue doesn't resolved

What I did after I changed my streaming software
I was using streamlabs before then I shifted to obs
Obs is a little better but didn't fix the the issue
So issue still not resolved


After that I thought may be my laptop audio jack port is not working
I changed the laptop
I tried all the things on my bothers laptop but still issue is not solved


Can you please guide or give something why issue is coming and how it can be fi
xed
I will be great full

Don't ignore the pinned post in this forum about posting your OBS Studio log when asking for help

I was initially thinking physical mic port, but obviously you tried a different computer... so that's eliminated

Real-time video compositing is computationally intensive. Adding audio filters and effects, as well as video effects (ex chromakeying) can make a using OBS Studio (or any other similar software) that much demanding on hardware resources (CPU, GPU, RAM, disk i/o, etc)
Did you recently try using nVidia noise reducer?
So a driver or Operating System (OS) update, or security software, etc change could have pushed you from being ok, to not. And there the issue when OBS Studio changed UI code with v28, breaking most plugins. so there are lots of possibilities

I'd start with tracking ALL of the plugins you are using. disabling all of them, and doing a test recording in OBS Studio and see if mic drop persists. And have Performance or Resource Monitor running while you are at it. IF you still have the issue, then the issue may be (or maybe not) the plugin still running.
In which case testing with a plain OBS Studio portable install with NO plugins at all... and don't use the Application Audio capture (BETA) feature

About cpu performance its not much just gain and noise effect is applied to audio
About video it's just a chrome site which is mostly not charging frames much.
But have seen drop in frames in live stream
Yeh obs is updated
No plugins are installed
Drives should be updated as windows does that automatically or at least ho support software gives a notification
I am using connxent audio drives ....
I also have a +12 mic gain in setting of mic from windows.
