Sooo... I have optifine and a shader, everything was working fine when I was playing yesterday and this morning, and then when I logged on again, my sound was gone. This happens a lot, it's always fixed by either just closing minecraft and starting it again, or restarting my computer, but after multiple restarts it still wasn't playing audio, I just switched the profile in the launcher from optifine to the vanilla profile and the audio was back, switched it back to optifine, gone. everything's up to date, anyone know how to fix this?
