Not sure if its related, but I have the Dolby Atmos enabled in the settings.
The bugs I experience literally every single match are:
1.Sounds randomly are not playing. This includes the countdown, sometimes Athena even skips one of the counts
2.Not related sounds being played. For example I was in the spawn, our team Mei killed enemy Reaper far away from the spawn but I heard Reaper’s death voice as he was in our team and he died very near-by
