Assessment

Difficulty: 2/5
Estimated time: 1-3 hours
Newbie friendliness: 35/100

Issue type: Bug
Clarity: Mostly clear
Activity status: Stale
Tech stack: java
Domain: audio-video-rtc

Research direction

Start in AudioAnnunciator.java at createMediaPlayer, which the stack trace identifies as the point where JavaFX Media receives the file URL. Read the related issues #3142 and #3058 for context, then check how a path containing spaces is handled. Done when the annunciator can create a MediaPlayer for the reported path; linked pull request #3993 is already open.

Written by the indexing model from the issue text.
