S440 - HDMI sound output problem

Dear Lenovo-Community,

 

I have the problem that when I connect my laptop (s440 with "conexant HD audio") via an HDMI cable to a TV, then it only delivers the video signal to the TV but not the audio signal. When I right click on the audio symbol in the lower right corner then it says "HDMI not plugged in". I will add a picture of that. I already tried on different TVs but its

consistenly the same problem.

 

Thanks for any help,

Adrian

Hello Adrian123123,

 

seems you have installed Windows 10 right?

 

If yes, did you install the newest driver for the AMD graphics card from lenovo?

Because the hdmi soundoutput is coming from the graphics card, not the conexant sound card.

No I did not yet install Windows 10. I still use Windows 8.1 pro. Should I still download that newest driver?

Thanks,
Adrian

For Windows 8.1 the newest driver from lenovo is:

What version do you have installed actually?

I have this exact evrsion installed. Why would it be the video driver causing the problem, because the video output works perfectly. Its just that no audio signal is delivered, so shouldn't the problem be the audio driver?

No, the audio driver is responsible for the sound from your computer.

But the sound which goes over hdmi is delivered by the graphics card.

 

Maybe you can try install the newest driver directly from amd.
