Regarding the audio bug if this is a major concern for you, you can replace the current executable file with the one from an older version

I’ve tried it myself: overwriting with the old version of the .exe file works. There are virtually no other issues—no crashes, the gameplay is very smooth, and there are no audio bugs.

Of course, the downside is that you cannot play online with others, due to the difference in versions.

I honestly didn’t expect this issue to still be around after all this time.

As for how to find the old version of the .exe file, I went back to the previous version, but because I am Chinese, I can’t use any cloud storage tools outside the firewall. If needed, you can teach me.
Alternatively, you could try searching on Google for how to roll back to an earlier version.
