I apologize if somebody already posted about this but it's started to really affect my games and make LoL much less enjoyable. I don't know why, but every so often (maybe 1 out of every 5 games) I get no audio at all during games. This has only happened at Summoners' Rift so far, but it's throwing me off a lot, especially because I can't hear pings. Has this happened to anyone else and have you found a solution? The same thing happens for me with Youtube every so often also.

I have a similar issue, occasionally during my games the sound will cut out, and go from 100% to 20% which almost sounds like it is completely gone. It happens when I'm spectating, and playing. I found out that in the sound settings you can disable the sounds of the game, and then turn off that setting and it fixes it. It's really annoying though and happens sometimes 2-3 times a game.
