Sound playback bug(s)

• Aug 19, 2022 - 19:33

I'm transcribing a short piece I wrote a few years ago in MS4 alpha 2 for testing purposes. The playback on my machine doesn't sound right at all. It's laggy and irregular. Adding pedal and accompaniment makes it even worse.

This is not the same issue as even this forum post, since I did set my buffer size to 4096 (max) and the sound quality improves, but the timing and regularity doesn't change at all.

I'm running this on an AMD Ryzen 7 3700X with Gigabyte X570 Gaming X motherboard's audio hardware. It shouldn't be this bad. I suspect something is doing way too much work during sound render in this example.

Attached the score (created from scratch) and here's a link to the score on for reference:…

First I'd like to know if this can be reproduced by anybody. If not, I'd have to check my sound settings.

EDIT: Forgot to specify OS: Windows 10 build 19044

I switched to the Windows partition, Rename the attachment to mp3. This is what I hear.

I can hear my issue in both Windows and Linux versions, however, the Windows might be a little more pronounced. The rhythm isn't smooth in the first part, where I added left hand and pedal markings, and the prall and mordent in that section is suddenly much louder than the surrounding notes.
