I can confirm that my audio also cuts but in the character selection screen. Also I have heard Zenyatta’s ultimate twice plenty of times.
The game needs optimization patch as soon as possible.
It’s mostly Zen, but I’ve heard it with Widow repeatedly and a few one off issues for other heroes.
Wait you have that 2 ? it happens to me 50% of the time when i pop an ult i hear DIE DIE DIE then 10 seconds later i hear it again wtf?
