It appears that version 1.4.3 pre-release 2 fixes my issue of no sound. This is only this version since 19w06a broke it. I see no mention of the fix in the change log for 1.4.3-pre2.
I have this issue, but I found that the last version that worked was 1.13.2 and the last snapshot that worked was 19w05a. Version 19w06a to 1.14.1 there is no sound at all.
