Hi All -

I'm setting up my vMix installation as follows:
* Local computer has 1 host (me), co-host calls in via vMix call. May have guest on second call-in.
* I'm using the RodeCaster Pro essentially as a mixer and sound effects playback tool. Will record shows on vMix computer

I'm confused about the different audio busses in vMix and how I can best utilise these. I'm guessing that I would use the headphones bus to monitor everyting including the audio generated by vMix for the caller audio, audio inputs from the RodeCaster, etc - vMix would create mix minus for each of the vMix callers, so no issues there I assume.

However I'm not sure if headphone is the right audio bus to use for vMix in this scenario. Also, I'm unsure of how to map the headphone bus to an audio output on the vMix computer - I have a sound card that has the usual green headphone/speaker jack, but not sure if there are better ways to monitor audio from vMix. I was thinking about monitoring headphones via the RodeCaster with the USB returned audio, but that creates echo and looping problems at least in the tests I have done so far.

Thanks very much for any ideas/notes on this -

Hi All -

Thanks for this - the issue is a delay in the headphone mix for my own audio. If I listen locally to the Rodecaster, there is of course no delay. But if I route the vMix Headphone mix to, say, a USB Focusrite interface and listen to the Master Mix via that (ie, Mic into Rodecaster, Rodecaster into vMix via USB, Headphone mix back to Focusrite via USB), my own voice is delayed almost half a second, which makes it difficult to monitor myself. I'm now trying running my own mic through the Focusrite, and setting up the Focusrite as an audio input device on vMix. The Focusrite allows me to listen to both the local mic signal and the USB return, so i have the USB return to the Focusrite set to Headphones in vMix and I have turned down the headphone volume for the Focusrite audio input in vMix so I don't hear both the local signal and the signal returned from vMix via USB.

I'd like to run my own mic through the Rodecaster, but I don't see any way to accomplish this without complicating things, since if I listen to the Rodecaster headphone mix, I have to route the rest of the audio from vMix back to the Rodecaster via USB which is creating the issues. Thanks for any thoughts on this!

In vmix call you can select the sorce audio used for your guests. By default it's using master. Change it to bus A and do a submix of all sources to bus A that you want the guest be able to hear.
