Description
Describe the bug
Listen to the short guitar excerpt in the attached MS3 file. Notice the shared noteheads and the fact that the volume is consistent throughout.
shared_notehead_playback.zip
Now, Play back the same file in MS4.
RESULT: The volume is inconsistent. It sounds as if it is louder on the shared noteheads then diminishes on the single notes following them.
Expected behavior
The volume should be smooth and consistent, as it was in MS3.

Start by opening the attached shared_notehead_playback.zip and comparing playback of the excerpt in MuseScore 3 and MuseScore 4, focusing on shared versus single noteheads. Trace the playback path responsible for the differing volume, and consider the issue complete when the excerpt plays with smooth, consistent volume in MuseScore 4.
