GAMEPLAY - TFT Sound bug

I was playing a TFT game and had clicked on the Fiora I had on the TFT board (not the bench) during the preparation period before the next round of combat. I had expanded her ult description so I could read it in full and still had it open when my team got pulled to another arena. The ult description changed shape briefly from long and narrow to more of a square, then changed back. I clicked elsewhere to get rid of the expanded window, and when combat started there was no sound at all, until Fiora died.

Don't know if it was a one time thing or not, but wanted to put in the report. 1.)Click on Fiora on the Arena 2.)Click on ultimate ability 3.)my team gets dragged through the portal to another arena 4.)Close ultimate ability window/Champ window

Result: No Sound

5.)Fiora dies during match

Result: Sound returned.

I haven't tried to duplicate it as it was my last game of the night.

Thanks
