SO I recently decided to get back into playing mod packs and the first thing I noticed was that there were no sounds, normally I would think this was just a glitch a reload the modpack but upon doing that there was still no sounds. I have now tried this with 2 other modpacks and I still had no sounds if this is a bug is there anyway to fix it I have tried reinstalling the launcher and there were still no sounds
