Audio Bugs random global champion talking 6.8

After downloading patch 6.8 I have been hearing team-mates and opposing opposition randomly global taunting me or just saying there casual walking animation line. So far being top lane I have heard our Twitch ADC talking and Sion in our team jungling I will hear them from top lane talking like I was playing the champ myself even when I haven't moved my camera from being locked on my target champ down to bot lane. This only seems to happen at the start of Summoners Rift before the minion waves reach the opposing teams minion wave
