Can’t connect audio to my friend’s twitch stream.

Well if he's streaming on twitch you need to be in a party with your friend. Once you are... open up the party where it shows who's in the party and etc.. there should be an option where it says "Include my audio" Click it and your audio should be joined in with the stream.

If you are live streaming on Twitch you must use the twitch settings. When you stream on Twitch in a party everyone in that party must “include audio” for it to be heard on stream.

Thank you for your assistance.

We solved half of my problems. My audio is now streaming to twitch. However, game chat is not. Last week on I was able to stream my mics audio AND my IN GAME chat audio to twitch directly from my Xbox series S, meaning my PC and Playstation party mates audio was making it into my stream.

That is not happening now. Slightly less frustrating but still quite.

he is on pc and my audio goes through on his stream fine but his will not go through to my stream and on pc he does not have the option to include his audio. and he uses stream labs for his stream but i stream straight from twitch.

nope as twitch streaming pn PC has nothing to do with Microsoft or the gamebar so cannot be blocked, you would have to ask your friend to not broadcast the audio but that may also affect game audio too.
