I have officially given up for now… I called Oticon to ask about New LE Adapter and they said to check with my hearing aid professional… I told them my hearing aid professional said to call Oticon… whatever … I’ll wait to see if audiologist has any luck finding out about the adapter … I can’t afford a new laptop and I still don’t know if LE audio supported laptop will mean that others could also hear the audio …
I am still not sure we (or at least I) fully understand your use case. What I think you are trying to do is connect to Zoom call using your laptop but there are others also in the same room also using their laptops to connect to the call (and presumably others remotely). Does the room have speakers through which the Zoom call is playing for the rest of the people in the room? If so it does not matter how you connect your hearing aids (Bluetooth LE to laptop, Bluetooth to phone connected to same Zoom call, etc) you will get feedback / echo when you unmute yourself. Your mic in the hearing aids will pick up the room audio and feed it back into the room audio). The only way to stop this would be to disable the mic in your headphones for the Zoom call and use the same audio input as the others.
If, however, all you are trying to do is connect to Zoom call with everyone else remote then this should be pretty easy to achieve. As others have said Teams allows you to connect one or more devices to a call (or swap between devices) and you can disable to audio in one of the connections. I am pretty sure Zoom could do the same. However you say you get echo / feedback when you speak using a phone connected to call (suggesting that you do have the use case described on the top of my post).
Likewise if everyone else in the room is also using headsets / earbuds to connect to the audio, this should also be fairly easy to achieve using your phone or an adapter. In this case your mic should not be causing feedback / echo.
Maybe you can clarify the exact use case.
Thanks
