The only thing I can think to cure this is for someone to upload the required sound files and give me the link.
I've tried restarting multiple times & i've tried resetting the pack. The files are just not downloading and i'm getting frustrated because I just started a new world.
The sounds were there before but then I finally updated it and now there are no sounds whatsoever.
I know it's not my computer because I have the regular minecraft launcher and it updated just fine.
Please someone help me.
