Question / Help Can't Hear Audio with Video Source

[MaowPurrHiss]

I'm confused. Shouldn't I be able to hear the audio that is coming from a video in the preview?

My media source is using a local MP4 video. When it runs in the preview... I do not hear any audio.

The MP4 file plays fine in a desktop player (you can hear audio from the video in that case).

How do I know what the broadcast will be like?

Hey there!

So what worked for me with using my video capture device with my Nintendo Switch to computer was going into the cog looking settings for your video source. Then from that menu, scroll to the bottom where it says 'Audio Device' and select your 'Digital Audio Interface (USB Digital Audio)'. Then make sure that your sound is able to be heard from your monitor and output (usually this is turned off so audio isn't doubled over streaming) by clicking the setting cog for your 'Audio Mixer'. From there, find your 'Digital Audio Interface (USB Digital Audio)' device, click the drop down options under 'Audio Monitoring', and select the option 'Monitor & Output'. I hope this helps!

By default, media sources only play out on the stream, not to the local speakers, as that would cause audio doubling with the assumption OBS will be listening to/capturing audio over the default audio output device.

You can go into Advanced Audio Properties (click the cog in the mixer) and set the Media Source to 'Monitor Only'. Then in the Settings->Audio, under the Advanced block, set your Monitoring device to your desktop speakers. This will play the audio back over them (so you can hear it), OBS will capture that audio on the Desktop channel instead of direct-playback, and send it out to the stream. The only issue might be a few milliseconds of audio desync (maybe).

very helpful!
