Suddenly, in the middle of playing, the sound in Minecraft stops. Tried F3 + S/T, and to top it all off, this is what the volume mixer looks like (Sorry for the non-English language).
Minecraft version 1.10.2
Using Windows 10 (Did not have this problem before windows 10 update)
I am using a school pc, so specs are not great, but Minecraft runs fine.
While researching if people had a similar problem, I found no one whose sound suddenly stopped mid game. Also, I haven't seen anyone with a volume mixer like this. It is constantly at max, not changing at all, and no sound at all. (Other sounds work fine)
Restarting my PC fixes the issue, but only temporally. Any ideas?
