For reference, this is the xCloud version of the game which, as far as I know, is simulating an XBOX Series X.
Issue: Both at community and official servers, my VOIP simply stops working in game, resulting in no input and output of voice and microphone being recognized by the game - so, I can't transmit any microphone sounds to the game / other players and also cannot hear any other players through VOIP.
It seems (but requires further testing to be sure) that this is related to joining a Party in the Xbox (party is pretty much a group in which you can talk using your mic while playing, like getting into a Discord call), due to some important points:
- Microphone / VOIP do work sometimes (so it's not related to the xCloud not recognizing there's a mic connected), this can be verified by, with the microphone / headset connected, going to Options --> Sound, and checking if the input bar in this menu page moves when you tap or make any sound close to the microphone; this can also be confirmed by listening to other players talking in game
- Party Chat disables microphone output into the game while in party chat: so, if you're in a party chat, although you should be able to hear players in game, you cannot transmit your microphone sounds even if you press the in-game push-to-talk key (this is an Xbox / Console limitation), so for you to communicate in game you must either leave the party or go to the party options and change to "Game Chat", now whenever you use your microphone, it's audio will be sent to the game and the party members won't hear you through the party
- Issue related to joining a party: as I've said, it requires further testing, but this bug appears to happen after you join a party. After you do, even if you switch to game chat or leave the party altogether, in the audio options menu you will see the microphone input bar will NOT move regardless of how much noise you make near the mic and you will also NOT be able to hear players talking in game - as if the VOIP system was simply turned off to you.
The solution here is restarting the game and, apparently, not joining a party.
I'll classify this as a Major severity due to this issue making it near impossible to have any proper player interaction and to play on PVE / RP servers.
