Minecraft 1.16.1 No Sound

I've been playing on an single player world since 1.15.2. It has had sound but when MC updated to 1.16.1, I haven't been able to hear anything. Additionally, subtitles don't work. I've tried F3+T, messing with volume mixers, restarting my computer, reinstalling MC, etc. I crashed my game to get a report but I don't know how to use it to my benefit. I changed my options.txt into options_old.txt and it doesn't work. I've made a new world, yet sound and subtitles still evade me.
