Coincidentially i have the same laptop (but a different TV).
I'm using default audio drivers coming with W10.
Probably you need to set standard device in sound control panel manually.
I add a screenshot for reference.

Thanks for this Stefan. It seems in Germany you are very lucky.. I've attached my equivalent screenshot. You'll see that your Audio-, Video- und Gamecontroller entry shows Intel (R) Display Audio and Realtek High Definition Audio. Mine contains (Microsoft) High Definition Audio Device and Realtek High Definition Audio. And that is what believe my problem is. The (MS) HD Audio Device prevents the Intel Display Audio driver from running and prevents my TV from appearing as a device for audio playback. It's the same for other TVs that I've tested - Panasonic and LG.
Problem Solved. On several previous occasions I had tried reinstalling Intel (R) HD Graphics Famly 220.127.116.1148 without it solving the problem.
This time I (re)installed the Intel Chipset Driver 10.1.1.7 first and then reinstalled Intel (R) HD Graphics Famly 18.104.22.16848 and ...... bingo ...... the Microsoft HD Audio Device had disappeared and my TV showed up as a device for audio playback with sound on the HDMI connection.
I would like to know if the information provided to you was able to solve your concern?
In case if you need further assistance do not hesitate to reply back.
I am looking forward to hearing from you.
Stefan3D's reply didn't solve my problem but it prompted me to try a few different things as a result of which I stumbled upon the solution described above.
