I have downloaded the latest vMix beta trial and am attempting to set up an output stream through the hdmi port of my Thinkpad to go into a LiveU LU600. I can get video out but it doesn't seem like I can also get the associated audio out. Also don't seem to be able to setup an input stream with hdmi camera in which has both audio and video. I see the video, but no bars on the audio. I am bringing in a GoProp Hero6 as a test, hooked up through the hdmi port to a Magewell usb capture hdmi 4k Plus. I would gladly pay someone to walk me through walk me through this to see if this works before I buy the program.
