The function is audio into TV speakers
The checked Hisense VIDAA U8.5 manual describes Music Sharing as playing mobile-device audio through the TV’s built-in speakers. It is not a screen-mirroring procedure. A Bluetooth audio connection therefore does not establish that a phone’s video interface should appear.
Identify the desired task. Listening to music, sending a media item and mirroring the whole screen are different routes even when the same phone and TV are involved.
Check the direction and output
For the manual’s supported Music Sharing route, the TV speaker output is part of the documented arrangement. Confirm where the sound is supposed to play rather than pairing more devices indiscriminately.
For a screen or video task, use the supported sharing technology in the exact TV manual, such as its documented Screen Sharing or AirPlay route. Do not rename a Bluetooth pairing action as casting.
Keep the regional scope
The cited source is a Malaysian VIDAA U8.5 manual with model and territory limitations. Check the actual European model’s features before buying an accessory or promising either direction of Bluetooth audio.
A precise report says that phone audio reaches the TV but video was expected. That makes the feature mismatch understandable without claiming the working Bluetooth connection is broken.
Questions answered
Should a phone picture appear through Music Sharing?
The documented feature concerns audio, not screen mirroring.
Does every VIDAA model provide this function?
No universal claim follows from the manual; check its stated model and regional limits.
