This script has the advantage of making audio from the HDMI stream available to voctomix, so that audio and video are in sync.

Diese Beobachtungen legen nahe, dass das Problem nicht alleine am Kabel noch am Tronsmart und vmtl. auch nicht an der Karte liegt. Warscheinlicher ist eine Kombination der Faktoren mit Umgebungs-RF, | ||
