... since the beginning I always get a No audio from partners...

And what does your Solo Session report? Does it work for you? I think that if Solo Session works for you, then the "no audio from partners" is on their end. Last I successfully tried (several weeks ago now), it all worked for me fine. Then, with no configuration changes, I tried again a week later with my brother and one other. The one other and I chatted just fine, but my brother could hear us but not transmit to us. We believe the issue is somehow on his end, but he's not been able to crack it yet.

Good luck -- write back with good findings!
