Some findings:

This works in Emulator when run from source, but does not work in a production build.

[tonyanziano]

We think that this might have something to do with the internal Electron build that we use in the production app of both Emulator and Composer.

The internal build we use might be missing codecs used for certain audio / video playback such as .wav files.

For reference https://microsoft.sharepoint.com/teams/ElectronInMicrosoft/Wiki/Electron-11.2.3.aspx. We currently use the electron version with no FFmpeg codecs. Production support for playing audio files/video files inside Webchat can be supported only if we use a media flavor of the Electron in our build pipelines.
