It's been a problem since before LSI merged into Lolreplay2, and it's still around. Out of nowhere audio starts playing super loud when i'm not even playing league. Sort it out, because this shouldn't even be an issue.
Same, I won't run this until the audio ads quit playing. Its bad enough when you are not playing league, but it horrible with you are playing and suddenly this high volume ad starts blaring in your headset, drowning our voice coms and game sounds.
