Blender Version
Broken: version: 2.93.0, branch: master, commit date: 2021-06-02 11:21, hash: rB84da05a8b806
Worked: (newest version of Blender that worked as expected)

Short description of error
I tested the script to play the audio, then the rendering is complete.
Audio module "aud" not play sound in Blender 2.93 or play sound randomly
Tested on Linux in Blender 2.93 - same problem
Tested in Blender 2.92 - works

If change: Preferences- Sound - Audio Device - from WASAPI to OpenAL - works

Exact steps for others to reproduce the error

1. Open script "Play_sound1.py"
2. Set in "path" variable your path to sound file "play.mp3"
3. Sound not play or play randomly

[Based on the default startup or an attached .blend file (as simple as possible)]
