[Problem/Bug]: Can't change Audio Volume in Xbox

[elmanuelv]

What happened?

I have a project with music and an option to change the volume.

When running Visual Studio 2022 it works perfectly fine. But when I export as a UWP package and port to Xbox, the music stays always at a constant volume.

I was able to find a minimal repro for this:
xbox-issue4330.zip

I have reproduced the issue with both the originally provided files and the minimal repro. The problem occurs with using AudioContext's createMediaElementSource() method. If that is used to connect a media element to an AudioContext gain node, then changing the gain node's gain seems to have no effect on the output audio volume. When previewing on a Windows device it works correctly (as it does on all other browsers/platforms); running exactly the same files in WebView2 on Xbox shows the issue where audio volume is not altered. (Note you must click or press a gamepad button to start audio playback.)

This is important for all content made in Construct as it plays music and controls the volume using this approach.

Hi @elmanuelv,

Thanks for reporting this and I've repro'd this behavior as well. It's been added to our backlog!
