Symptoms

Game loads and plays somewhat fine. The issue is that the Music track plays correctly, but most (if not all) sound effects are not played. Menu audio is missing, button click "event" audio is missing, etc.

Reproduction

1. Install
2. Run
3. Scroll through the menu
   • Realize half the audio experience is missing.

Other Issues

1. Multiple reports of missing movie playback

Possible fixes

A ProtonDB user reports that installing XACT manually into UMVC3's prefix will fix the issue. This might indicate that corrections to Proton/Wine's XAudio implementation could end up fixing this game straight into "Test for Whitelist" territory.

Start by reviewing the linked Proton log and the report's notes about missing sound effects, XACT, and Wine's XAudio implementation. Reproduce the game-menu behavior described in the issue and investigate whether the missing effects can be traced to that audio path; done means the affected menu and sound effects play correctly.
