I have a Samsung Qled QN93 with a Sonos arc and 2 sonos ones as a 5.1 setup connected through the HDMI earc port. As a audio format option i use passthrough, and this is working fine with my Playstation, external tv box or other device. But when i use tv apps like Netflix or Prime Video i noticed that the audio format setting keeps changing to auto and the passthrough option is greyed out.
