Hello, the sound quality from my Era100s is terrbile when the audio is coming from the TV. It has always been like this. Difficult to describe, but it sounds very quiet and very, very rough. When playing from the Sonos app they sound like they are supposed to (loud, crisp and clear). My setup:

TV LG OLED48C14LB

SKY Stream

Beam (Gen2)

Sub Mini

Era100 x2

HDMI 2.0 cables

The TV is connected to the Beam via the HDMI2 ARC port, and SKY Stream via HDMI1. The Beam is connected to the router via ethernet. The Sub mini and Eras are wireless. The TV “Sound Out” is set to “HDMI(ARC) Device” and “DTV Audio Setting” is “Dolby Digital Plus”.

Is my setup at fault, or can anyone give me advice? It does strike me as odd that there is a fault somewhere with hardware or software. Could it be that the HDMI2.0 cables have to be HDMI2.1, as the only material difference between the audio coming from the Beam itself or the TV is the TV itself and the cable(s). Thanks for any advice.
