Bug Report Crackling and popping audio when I type while recording

[adibacco]

OBS is normally working fine (recorded audio is fine). If I try to speak while I'm typing then the audio starts to pop and crackle. When I type the computer doesn't emit any sound because I disabled System sounds. The CPU usage shown by OBS is something 4-5%. OBS version is 22.0.2 (64 bit, win10)

Check that the sample rate for your audio devices including microphone are set to the same sample rate as OBS is (either 48 or 44.1).

I love audio bugs, it sounds like they are competing for USB resources.

If both keyboard and mic are running on the same USB hub try to separate them. If possible you can try to reduce the polling rate of the keyboard as well if it supports it.

Thank you to everyone.

I followed your advice about Game Mode, Game Bar, Game DVR. My FPS is 30 fps with 1920x1080 screen resolution, OBS is configured with the same sample rate of windows (48 kHz, 24 bits).
The problem still persists (see https://youtu.be/lG9k8mOuX84 ).
My PC is a Dell XPS 9560 and the CPU usage is negligible when recording video anyway it is impossible to record a proper video. Don't know how to lower keyboard polling rate.

No such thing on a laptop, only gaming keyboards typically have control over it and not always.

Is there any OBS developer that can understand what's going on? I believe that it is impossible that OBS doesn't work on a PC (Dell XPS 9560) that is not so old or low profile after all.

Can you post a log? I am not sure how helpful it will be, but the suggestions already made are the most common audio issues, and most other audio issues actually occur upstream of OBS.

That you say it particularly happens when you type is interesting.
