What is the best solution for setting up audio for multiple canvases?

[istvanmate]

We have 2 canvases: stream and record, the difference between them is one Outro scene, that plays on stream but it is replaced by Kamera1 scene on the record. For this we need to separate the audio as well, to not play anything on stream from the mixer while Outro is playing, but still have the mixer audio on the record canvas.

Current audio is set up like this:

[Sound Sources] (scene)

• [ASIO/Dante Ch1-2] (source, atkAudio Source Mixer plugin with atkAudio DeviceIo filter capturing audio from Dante Via ch1-2 with ASIO)
• [ASIO/Dante Ch3-4] (source, atkAudio Source Mixer plugin with atkAudio DeviceIo filter capturing audio from Dante Via ch3-4 with ASIO, not relevant here)
• [Studio Monitor] (source, atkAudio Source Mixer plugin with atkAudio DeviceIo filter sending audio to Dante Via ch1-2 with ASIO, assigned to OBS track 2 in Advanced Audio Properties)

[Sound (Stream)] (scene)

• [Mixer (Stream)] (source, atkAudio Source Mixer plugin mixing sound from sources ASIO/Dante Ch1-2 and ASIO/Dante Ch3-4, assigned to OBS track 1 in Advanced Audio Properties)
• [Sound Sources] (scene, for having the audio sources loaded in)

[Sound (Record)] (scene)

• [Mixer (Record)] (source, atkAudio Source Mixer plugin mixing sound from sources ASIO/Dante Ch1-2 and ASIO/Dante Ch3-4, assigned to OBS track 6 in Advanced Audio Properties)
• [Sound Sources] (scene, for having the audio sources loaded in)

Now, we have each scene set up to include the [Sound (Stream)] and [Sound (Record)] scenes, except our [Outro] scene, which only contains [Sound (Record)] scene and have the sound of the outro video go to OBS track 1 only.

My issue is, that when we switch scenes, the sound glitches, every time. Most probably because the sources are being unloaded and instantly loaded back in (?). We switched from Andersama/obs-asio, because our OBS is crashing and was told by the Aitum crew to update our old plugins. Also having a mixer as a source is quite overpowered. Nevertheless, we did not experience this with obs-asio.

Hear it in action. Any help is appreciated.

Hard to tell. I use a separate scene for audio sources as a subscene in other scenes.

Hard to tell. I use a separate scene for audio sources as a subscene in other scenes.

So, same as us? [Sound (Stream)] and [Sound (Record)] are audio only scenes nested as subscenes in our other scenes. Do you also use ASIO to capture sound? Do you notice dropouts when switching scenes?

There's a bug when "Follow Scene" option is enabled in DeviceIo. Turn off Follow Scene, and transitions should be clean/continuous. When Follow Scene is enabled, there should be a fade, but instead we get a glitch.

Thanks. Will try and report back!
