TCL TV, Sonos Beam and Oticon Hearing Aids

[u/teamcooperuk]

I’ve been trying to solve this problem for my in laws for a few weeks and I’m getting nowhere.

They have a Sonos Beam connected to a TCL 735 tv via HDMI/eArc. My father in law has Oticon hearing aids and there is an Optical cable running from the tv to an Oticon “Box”. The hearing aids connect to the Oticon Box via Bluetooth.

I cannot get sound to output both to the Beam and the Oticon box (the hearing aids are connected).

What is odd is that this used to work. When they first got the Beam I had the setup as it is now, and TV audio would play out through the Beam and the hearing aids. It was only a month ago when I connected my Bluetooth headphones to the tv and then set everything back that suddenly the hearing aids were not receiving anything.

I bought an “HDMI eARC (CEC) audio extractor) but that’s not working either. The Sonos app shows that it is receiving audio and the tv remote changes the tv volume, but there is no sound through the hearing aids or the Beam.

Does anyone have any experience of solving this problem?
