This may be the same issue as #94226, in which case it would be fixed by #94268 (in upcoming 4.3.rc1).

Doesn't seem fixed yet, I can confirm the bug in 4.3.rc2.

I tested and confirm that the issue comes from Web audio now default to "Sample" playback type, which is new in 4.3.
Overriding it to "Stream" (i.e. like in 4.2.2) works around the issue.
