Is Laptop Party Audio Included in Twitch Stream if Streamed from Console?

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.

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.

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.

this feature have been added to Mixer, but not sure about Twitch

Mixer only has a setting to include xbox party chat audio on stream, not game chat audio

When you stream through Xbox there is a setting in the twitch app to include party chat. But the party members have to allow their audio to be used. If you have “Party Chat” muted on the broadcast screen (it's in between “Microphone” and “Game”), or won't have the option to include audio.
