TLDR: Audio drops out while using audio-interface with OBS Studio and OBS Studio only!
While using audio-interface Behringer UMC204HD with OBS Studio, audio (both microphone and windows audio tracks) constantly and randomly (every 3-5 minutes) drops out for a short period of time, which sounds like stutter or click. On the spectrogram it looks like this:
Most of the time the length of these drop-outs is 20 ms.
These steps were taken in order to localize the issue:
Now let's look at situations when this DOESN'T happen:
I guess this might be some algorithm/codec/core process of OBS studio (which apparently absent in Classic version). What could that be?
After all these tests I plugged in my Blue Yeti USB microphone - same issue. Audio drop-outs while using OBS Studio. Then I managed to find another interface (borrowed an ancient M-Audio Fast Track from a friend). Same again. With the last 2 devices these drop-outs were somewhat rare though.
Another thing. One time I was able to reproduce and intensify these particular 20ms drop-outs by messing up sample rates (48000 in one setting and 44100 in another). Maybe this suggests something in OBS recording/encoding/syncing algorithms makes audio-device to re-switch its sample rate?
What's going on here? This is a serious flaw that should be addressed ASAP!
I was on the brink of buying another interface, but now I understand there's zero point doing that.
There were quite a few topics about same issue, with this one most similar to mine:
Thread
I attached the log but obviously everything's fine there.
My system is Windows 10 21H1 and CPU - i7 7700K.

These steps were taken in order to localize the issue:
- trying different USB-cables
- trying different USB-ports, as well as self-powered USB-hubs
- running OBS with Admin privileges
- trying different OS, PC, notebook
- setting different sample rates (44100/48000)
- trying different windows audio optimizing guides (High Performance mode, disabling USB power management etc.)
- routing everything through Voicemeeter Banana in every kind of way (I promise I tried everything in there)
- routing mic signal via VB-cable through Reaper
- trying different codec (x264, NVENC), FPS, way of audio capture (settings vs source)
- trying ASIO capture plugin
- trying ffmpeg with WAV (PCM) as audio codec
Now let's look at situations when this DOESN'T happen:
- while recording in a DAW (Reaper, Adobe Audition, Audacity / ASIO, WASAPI, MME)
- while recording in XSPLIT (!!!)
- while recording in OBS Classic !!!!!!
