It's not just the "choppy" sound etc that he's talking about I'm sure.
Voice chat is incredibly buggy right now all around. Changing channels can result in losing ALL channels and needing to actually shutdown the PS4 completely (a re-log doesn't clear it). Getting perpetually stuck in the "joining channel" countdown is a regular issue I've experienced from day 1 and still experiencing it at this point too
Sometimes shutting down the PS4 doesn't help, and we've had guild mates shut out of chat for several hours at a time.
