In this video I describe (in Portuguese) how to setup a system to record PC sessions (mostly game sessions in my case) using Avermedia LGP with 2 audio outputs (USB Headset and HDMI) and 1 audio input (the mic of my USB Headset).
That's because I need to listen to all the game sounds on my headset and at the same time I need those sounds to be received and recorded by my LGP (over HDMI). I also want the LGP to record what I say (on my mic) during the game sessions.
If you need a setup like this, then this is what you should do:
1- install Voicemeeter on Windows
2- open Playback Devices and configure VoiceMeeter Input as default sound device
3- go to Recording tab, right click on VoiceMeeter Output and choose Properties
4- now click on the Listen tab, check Listen to this device and on the dropdown menu, choose your HDMI device. Click OK when finished
5- on VoiceMeeter (the software), select your mic as one of the Hardware Inputs
6- then in the Hardware Out section, set your headset as one of the outputs.
Done, now you have the game sounds on your HDMI device and the Headset, plus the sound of your mic ONLY on the HDMI.
