is an audio “break-up”, your getting but not sending and unlikely that any form of jitter buffery can fix it coherently, it can reorder a few out of order packets and fill in couple but you need to fix your network , if QOS isn’t working then jb’s likely wont either and the quick diagnosis is it is your LAN causing the bottle neck.
