There are a few different options we can suggest right now
- Can you use TV remote control to set the TV audio output to OPT rather than HDMI when using Avantree headphone?
- How about add a HAX05 between your TV and your soundbar. Then you connect HT4189 to HAX05 instead of TV.
- We are working on a new TV set which support HDMI passthrough, HT7100, ETR 2024Q2, FYI
