Started to use OBS and two Logi 920 I have a pretty robust system but when i run in OBS at 1920x 1080 I get audio glitches stutters and drop outs when i drop it to 1280x 720 it seams to work ok , Ive disabled all the auto features in the 920 but I don't understand why this is happening in OBS it say my CUP usage is 1.9% Ive done pretty much everting I can imagine but still cannot get around the audio glitches any help or suggestion appreciated.

Post a log file please.

Also, are you trying to use the Logitech drivers for your 920's, or the standard UVC drivers? Also, you say you're getting audio glitches/stutters.... are you trying to capture audio from the webcam(s)? Or is this another audio device that is having the issue?

thanks Carlmmii , I just checked and the UVC drivers are installed, im also using 2 920 but happens wither I have one or two connected Im using a I-Rig to capture the audio off my mixer , ive done test capturing the audio on another device and its fine, there appears to be something happening when i change the video resolution to 1080-1920 that causes glitches. im stumped

My system is custom build I7 5820 30mghz with 32gigt of ram so have plenty of juice ,,,

For your webcams, don't use a custom audio device. Revert that back to the default device audio in your webcam source preferences.

Instead, either add a separate audio input source selected to your iRig device, or go to obs settings->audio and set one of your microphone inputs as your iRig device. This give the proper audio chain for your device instead of trying to shoehorn it through an entirely different USB device.
