Use OBS virtual camera in Google Chrome
Check OBS Virtual Camera selection in Chrome and verify microphone capture separately, with clear limits on what the supplied evidence confirms.
To try OBS Virtual Camera in Google Chrome, check whether the calling or recording page lists it among its camera choices. If it does, select it and check the video preview. For speech capture, also check the page’s microphone selection: a working video preview does not establish that your voice is being captured.
Check the microphone used for speech
If you want to use your webcam’s built-in microphone, look for the corresponding input in the page’s microphone settings. If you want audio processed through OBS instead, the supplied material does not establish a supported audio-routing method. Do not assume that selecting OBS Virtual Camera also selects the intended microphone or carries your OBS audio.
If the page provides a microphone level indicator or a test recording, speak and use that check to confirm that it receives speech. Where playback is available, listen for intelligibility, background noise and interruptions before starting the call or recording.
What remains unverified
No compatibility documentation, software versions, operating system details or test results were supplied. That leaves support for your particular Chrome setup, the availability of your webcam microphone and any OBS audio-routing requirements unverified. If the camera or microphone is missing from the page’s choices, those setup details are needed to identify a supported next step.
