Browser source - using "control audio via obs" - audio needs to go both into monitor device and obs app

[CodingAlbert]

Browser source - When "control audio via obs" is selected, OBS sends active scene (browser sourece) audio into monitor only. There needs to be an option to duplicate the audio into OBS app audio output.

User case: Streaming reaction videos on MacOS

Current state:
Sound technician uses `monitor device` to listen to overall sound quality including Moderator's voice.

When streaming in studio mode, sound technician is preparing the following scene and uses `monitor device` to listen to the active scene and preview of the new scene at the same time.

Only the active scene audio is streamed though. This currently works great.

Desired state:
Moderator listens to the active scene audio as an OBS app output.

Even though I route the OBS app sound to moderator's headphones, he cannot hear the active scene as OBS sends it to `monitor device` only.

A setup avoiding using "control audio via obs" option and does not work for this scenario as both active scene audio and the previewed scene audio would be audible in the stream when in studio mode.

So I suggest a feature that duplicates browser source audio into OBS app even when "control audio via obs" is enabled.

Hi there, I think you could go to Advanced Audio Settings of the audio source and choose "Monitor and Output" to make Browser source audible directly both. It will be pretty hard to control the audio if you want the source audio play even in Preview mode, because it will overlapse the desktop audio source. you should control them independently.

Good idea, however, I already use Advanced Audio Settings of the audio source "Monitor and Output" option for all sources. But that still sends the audio to monitor device only. I could let moderator listen to monitor and simply turn of monitoring of his voice, but then sound technician cannot control his mic output.

Sound technician needs to hear browser audio in preview, or rather cannot avoid it as the browser sources have autoplay enabled.

I have no concern regarding overlapping desktop audio source, I do not stream desktop audio at all. Desktop audio and audio from other OS apps can be heard only in moderator's headphones.

So, I found a workaround:

This addon adds an audio filter "Audio monitor." In the filter, I can choose a monitor device different to the default monitor device that is set in OBS app's Preferences.

I added the filter to the browser source. Then, I simplu added moderator's headphones as a monitor device and behold, active scene is being played to the moderator's headphones.

I also need to have a hotkey support to toggle the filter on when the browser source with the filter goes live and off again when it is not live anymore.

This addon does it:

I used scripts activated by custom buttons on my keyboard for pressing the correct hotkey combos.
