Party Chat audio issues - crackling/hiss when streaming using Twitch App - fine during gameplay

Some friends and I have been trying to stream our gameplay through our Xbox Series X machines via the twitch app and even though all of us are hardwired to the net, have decent headsets, nothing else streaming/downloading, the audio (while perfect while playing) has cracks and pops when rewatching the streams on Twitch. The host will always sound perfectly fine on the stream but the party audio fluctuates between ok and terrible. Scouring the web shows countless people complaining about this with no fixes. Before it's even asked: yes the audio settings via the twitch app are set appropriately, yes the audio settings via Xbox are fine, yes internet connection speed is high. This isn't an issue with the party chat not being heard(we know that every person needs to allow the audio to be heard) but moreso that it sounds terrible when the stream is replayed after gameplay is over. Sometimes the audio works for a few minutes and then mostly pops/crackle with everyone BUT the Party host.

The only "fix" I've seen is to hook up the Xbox via an external capture card, use OBS or Xsplit, and use Discord instead of party chat. This NEVER happened with MIXER (I miss you....) and only happens with Twitch OR just don't have party chat on stream (defeats the whole purpose of playing with friends). Even if there is no intention of fixing this, just to acknowledge this is an issue would suffice. You'd think with the power of the new xbox that problems like this wouldn't arise but alas here we are.

At this point I am not sure who to blame here? Xbox or Twitch .
