HDMI (audio) problem on Acer Aspire E5-571.

[idata]

I've just started needing (again) to connect my Acer to my Samsung TV via the HDMI socket. There's no audio being delivered to the TV. I think the problem is tied up with the following:

The last time I needed this facility was when my OS was W8.1 and I remember the audio driver was Intel (R) Display Audio 6.16.0.3174. I'm now using W10 and my display adapter is using Intel (R) HD Graphics Famly 10.18.14.4282 which I think incorporates Display Audio 6.16.0.3174. My Sound Controllers under W10 include Windows High Definition Audio Service which I think is suppressing/overriding Intel Display Audio.

Is this a correct diagnosis and, if so, can anyone suggest a solution? (The Windows HD Audio Service reinstalls itself automatically whenever I uninsall it).

Thanks in advance for any help.

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.

What Display adapters are shown in your Device Manager? (You'll see mine shows Intel (R) Graphics Family.

Problem Solved. On several previous occasions I had tried reinstalling Intel (R) HD Graphics Famly 15.40.3.4248 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 15.40.3.4248 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.
