Issue description

setting a bus on an audiostreamplayer appears to work correctly when playing an audio in the editor but the requested bus is ignored when project is running

Steps to reproduce

1. add a bus from the bottom audio panel
2. create an audio stream node
3. set the node's bus to the desired one
4. run the project

Minimal reproduction project (MRP)

Thank you for reporting, this is a missing feature and is tracked here:

Consolidating there

Thank you for reporting, this is a missing feature and is tracked here:

• Make the editor's audio bus editor affect the running project in real-time godot-proposals#1186

Consolidating there

just to understand, the audio buses have no effect on audio in a project?

Please add a minimal reproduction project to make this easier to test:

• A small Godot project which reproduces the issue, with no unnecessary files included. Be sure to not include the .godot folder in the archive (but keep project.godot).
• Having an MRP is very important for contributors to be able to reproduce the bug in the same way that you are experiencing it. When testing a potential fix for the issue, contributors will use the MRP to validate that the fix is working as intended.
• Drag and drop a ZIP archive to upload it (max 10 MB). Do not select another field until the project is done uploading.
• Note for C# users: If your issue is not C#-specific, please upload a minimal reproduction project written in GDScript. This will make it easier for contributors to reproduce the issue locally as not everyone has a .NET setup available.

No worries, I'm not sure what I was doing wrong but I deleted the bus, restarted project and edited the default bus and it appears to be working now.

I will be testing things further and report back if there are any more issues

@ianmckenna87: How is it going for you? Did you have any more issues?

[AThousandShips]

Assuming this was a temporary problem, comment if you end up experiencing this again, but please add an MRP if you do so

I did some renaming with the bus and I still have that problem. it get's completely ignored. does it need to have a specific name?

[AThousandShips]

Please open a new issue for this, it's unrelated to this issue

ok, will do later:

just in case anybody has the same problem now:

I had to delete this from the .project and use the default name for the bus (default_bus_layout.tres)

[audio] buses/default_bus_layout=""

Thank you for this, I found out you can also fix this from the project settings.

Saving out a bus set with a different name appears to sometimes cause the default bus to blank?
