Thanks!
I used 4.3 because the web audio was much better than 4.2. There was a lot of crackling in 4.2.
Is it safe to disable sharedbuffersupport on itch with 4.3dev6? I saw it was being fixed but haven't tested it.
I'm not sure, I haven't compiled it myself yet. Dev 6 is supposed to have all the features, but lacking bugfixes of later versions. I would try it on a test itch project first to be safe.
