Bring the sound via Teams to participants

[Jürgen Burberg]

Hi,
since Corona I'v to do my seminars online. Now I faced the following problem: Video sound cannot be heard by the participants.
My setting:
- Win 10 prof
- OBS, actual Version (just downloaded it)
- MS-Teams Desktop Host

I defined a scene for Videos. But if I played the videos, sound cannot be heard. I can hear the sound on my loudspeakers, but not so my participants using Teams (some of them as a Desktop app, other within their browser).
Is there any chance to bring the sound to my participants?

Thanx!

You probably set your mic as input device for Teams, and this is the mic only. You need some mixer app + virtual audio device in addition to OBS to be able to provide mic audio mixed with other audio content.
Google for "obs teams" and you get a bunch of guides and examples in the first matches.

Well, thank you so far.
I googed a lot of hints, recommendations and reports, but I didn't find any solution for my problem, to pass video sound from OBS through Teams to my participants.
The problem isn't the sound coming from the mic. The mic sound goes through without any problems. The problem is that sound of videos isn't handled over to Teams. So my participants do not hear the video sound I hear as a host.
Maybe, there ar some more ideas?

If you play a video within OBS with a media source, the challenge is to get the audio out of OBS. As default, OBS outputs the audio to the recording or to the stream only, but not to any audio device on your Windows PC, so nothing can be heard.

If you open Edit->Advanced Audio Properties, you can set the Audio Monitoring setting from "Monitor off" to "Monitor and Output". The word monitor means OBS is playing the audio to the monitoring audio device, and the word output means OBS is playing the audio to the stream or recording.
The monitoring device is the tool to get the audio out of OBS to Windows. Install some virtual audio device like vb-audio: https://vb-audio.com/Cable/
Then go to OBS Settings->Audio->Advanced->Monitoring device and select the virtual audio device. Combined with "Monitor and output", you will get the media source audio from OBS to this device.
Then take your mic device in Windows audio control panel and locate the "Listen to this device" option. Activate it and select the virtual audio device as playback device.
Now you get both audio mixed on the virtual audio device, and you can select the virtual audio device as mic device in Teams instead of your original mic device.

Instead of using the "Listen to this device" setting, you can also use some mixer app like Voicemeeter https://vb-audio.com/Voicemeeter/index.htm , which also comes with an additional virtual audio device, to have more control over the actual audio mixing, especially audio volume, and which makes easier to add more audio devices to the mix.

The sound I get in Teams is distorted with Voicemeeter Banaa. If I activate a local speaker the sound is crystal clear, the mic, going through Voicemeets virtual device is great also, but the video source does not work properly.

Any ideas, wherer to finetune?
