Question optical TOS-link out to Bluetooth hearing aid transmitter

[Tonyw97007]

Here is our issue: we use a Bluetooth transmitter with some of our hearing aids. Whenever we connect a device to the HDMI ARC output, it seems to disable the optical output. We are using a Hisense 75U8H Google TV. Despite contacting Hisense multiple times, we have not received a clear solution. Is this an issue with Google TV, Hisense, or something else? Unfortunately, setting up various TVs in stores to test this isn't feasible, as I have already attempted.
