Question / Help Windows - USB bandwidth and Audio solution

[Babouc]

Problem with frame rates, audio. Nothing to do with OBS itself. OBS is great but windows audio is a mess.

Since I livestream conferences with different speakers, I need to adjust the audio for each of them. So I needed to monitor them live.

• windows 10 - 64 bits
• OSB - 64 bits
• Camcorder HD - HDMI
• HDMI to USB
• Web Cam - USB
• Second audio card
• Laptop i5 - 16G - SSD drive

I reinstalled windows 10 then installed the USBview monitor from Microsoft to make sure that the HDMI-USB and the WebCam-USB were on a different internal RootHub in my laptop.

The microphones are plugged-in into the external audio card. In OBS I assign this card to mic/aux. My headphone is plugged into this audio card.

For playing music I assign the internal audio card of my laptop to DeskAudio in OBS.

This gives me the result I wanted. No echo, direct live sound and go frame rate.

If you don't want to download the whole SDK, there's a simpler version of USBView for viewing which devices are attached to which hub on my blog. https://r1ch.net/blog/managing-usb-bandwidth-with-usbview
