Teams Live Events and audio
- Aug 02, 2019
There will come support for system audio in a meeting when sharing desktop soon in Teams meeting, even if they haven't specific said that it will also support system audio when sharing in a Live Event I think it will be supported.
We have used a HDMI to USB device for our customers that want to share audio from a computer, the device we used is from Magewell but there is many different brands. You have one computer where you present and share audio, connect computer with HDMI with the HDMI2USB device and connect the USB cable to and second computer. Join the live event as an presenter from the second computer, the screen from first computer will show as an video device and the audio will show up as an audio device/microphone.
If you want to show the presentation from the first computer on a projector screen or similar you have to split the HDMI signal first.
After searching on google I found a video on youtube below

The solution worked as well, but in my opinion it's still too difficult to be delivered to the user.
So I tried to find another solution that was simpler so that it could be done even by ordinary people.
The first option :
You need to prepare:
- 2 Notebooks
- 2 pieces of audio splitter, the price is around IDR 5K ($ 0.30) / pcs
- 1 pcs audio jack, the price is around IDR 5K ($ 0.30 $)
How to:
Using two notebooks that join into ms teams live meeting, where 1 notebook is for video and another notebook is for audio. Simply plug the audio cable from the first notebook speaker into the microphone on the second notebook. I have tested and worked well.
The disadvantages are:
because the two notebooks are close together, the microphone on the first notebook must be muted so there is no echo feedback.
Second Option:
You need to prepare:
- USB soundcard, the price is around IDR 60K ($ 3.7)
- Audio splitter, the price is around IDR 5K ($ 0.30)
- 2 pcs 3.5mm audio jack, the price is around IDR 5K ($ 0.30) / pcs
- External speaker, the price is around IDR 50K ($ 3)
Here's the config :
- Settings Default audio on the notebook to headphones on the internal soundcard.
- Connect the audio cable from the speaker port on the internal soundcard to the microphone jack on the USB soundcard.
- Connect the audio cable from the speaker port on the USB soundcard to the input jack on the external speaker.
- Default audio settings on ms team to USB soundcard
The disadvantages of these two options are :
Cannot be used to talk when broadcast video because the speaker and microphone are in use.
Please forgive my grammar because i am not good at english, hopefully it can help.

I made it working with a simpler configuration. Just used a piece of software called "Virtual Audio Cable" (https://www.vb-audio.com/Cable/) that is redirecting system audio to a virtual mic device.
indeed it's working even with one pc but every time I play a video into a live event I have to switch the mic configuration to "CABLE Output (VB-Audio Virtual Cable)", and remember to mute all the other presenters otherwise their talkover is cutting off audio from video playback.
