Hi friends!

After testing vmix's fully functional demo (one reason to be loyal!)
I decided that I actually needed something in between the HD and the 4k version
-I currently have no use at all for PTZ, Replay but I sure needed vmix call.

I wish they had an option to get more callers than 2 / without having to buy the pro version,
but that's ok..

Unfortunately I ran into some streaming problems which I didn't realize I might have, since while experimenting with the demo I never streamed live, and just tested with the recorded files instead and they were just perfectly working.

Well, I kinda embarrassed myself during my first livestream on July 1
because my microphone was quiet and viewers couldn't hear me, but the clips with audio worked.

Maybe there is someone here willing to help me understanding what I might have sone wrong, so I can finally start broadcasting soon.
I really read the entire documentation several times and watched their video how to's
so I don't think that I've done anything wrong in vmix but I believe something must be wrong
within windows or how I connected my microphone to the laptop maybe?


I try to explain the hard- and software I'm using:

---

I will broadcast to YouTube and I noticed it says they only work with 2 Audiochannels
While I actually had setup MAB in vmix (to have a talkback channel to my guests)

-Audio: I am using the Rode wireless mic (filmmakers kit)
It's plugged in to the mic input on my computer.

-The computer itself it a relatively new Alienware i7

-Cameras: I experimented with several GoPro5 Hero (wanted to use several video angles in virtual sets, but ended up buying two Logitech USB Webcams, who worked surprisingly well!
(I did deactivate their audio already, just using the video signal)

-Midi controller: I am using the Akai MPC MK2 and I can highly recommend it to anyone.
Unless you're a professional TV studio with top notch equipment I believe this is just perfectly working for me and I already midified all the activators and shortcuts as I liked them to be.
The only thing is that i wish I could simply connect the microphone here already but unfortunately that's not possible.

Output screen: For vmix and monitoring I use a 65"Sony Bravia plus a smaller 24"Vizio screen.
and here might be a problem already because I don't like to use a headset during production,
but listen to whatever is on channel M here.
I routed my Microphone to A. so I don't hear myself.
To reduce my microphone picking up noise from the TV screen, I either use a fader for my microphone or would vmix have mix the audio, so my mic would be muted during playback of audio clips whatso ever.
Still not 100% sure about how to handle callers then, since I need to be able to hear them.
Maybe I can learn from your experiences ?

Now describing the major problem I'm having:
I did a few tests yesterday and I can hearmyself speaking in the broadcast ONLY when i'm activating the Master channel for my mic, which immediatly results in a terrible echo.
Channel A seems not to be working at all. I also did setup in the stream options that it should send M+A to the stream. B is supposed to be my talkback channel with the guests.

Why Why Why is channel A not working, where could I possibly have missed to set up something?

Any help is of course appreciated!

I do a lot of work with callers and for me the busses work perfectly.

Things to consider for talkback
- Make sure the A and/or B bus is set to enabled.
- Disable auto-mixing on your talkback mic (the arrows button)
- Enable the channel (the loudspeaker button)
- Enable bus A on your talkback mic
- On the video call, rightclick and make sure its audio source is Bus A. Now your caller will hear bus A only (mix-minus). Make sure anything he should be able to hear is routed to bus A as well.

If your mic also needs to go to the master, change your speaker output to be headphones, and on the audio settings for your mic, click the "disable in headphones" button.
If you want to reduce echo, go into the mic audio settings and enable the noise gate, then set the threshold to be just above the level where it catches the speakers.

In my scenes I use a lot of triggers to enable/disable audio busses of individual channels depending on who needs to talk. This is an alternative to auto-mixing.
