Same here! Yesterday eve voice was gone to others and I couldn't hear anybody anymore either. I'm also on PS5 and I've never experienced this issue before not on D1/D2 nor on any other game. This happened when I was in a fireteam playing Pantheon and we died couple of times in Macrocosm 3rd encounter, then some left, one other player changed character and joined back plus other new lfg players joined in and at that time my sound to them and theirs to mine gone mute. I restarted my ps5, re-joined the same fireteam, left this ft then joined other fireteam, no progress in recovery of voice chat issue. I've also posted my issue just about 40mins ago, no response yet from Bungie, so I looked for others with this same issue and then seeing your post in here, neither you as I can see, has got any response from bungie yet. This must be fixed a.s.a.p.
