HP ENVY TS 15 Notebook PC: Problems installing audio driver (High Definition Audio device)

[r_singh_01]

Hello all,

My product is the HP ENVY TS 15 Notebook PC.

Product number: E3B65PA#AR6

OS: Windows 8.1 64-bit

A few days ago, I  upgraded my windows from windows 8 to windows 8.1 and found that no sound coming from the HDTV when connecting my HDMI cable however video is perfectly fine. I was completely baffled because the audio was working perfectly fine before upgrading to Windows 8.1. I have tried several solutions posted on other forums, such as installing other drivers, and uninstalling the IDT High Definition Audio Driver and then scanning for a hardware change. I have checked the HDMI cable and it is working fine with other laptop.

Device manager is showing 2 device :

  High Definition audio device ( Showing yellow traingle)

  IDT High Definition Audio CODEC

When I am opening the properties of High Definition audio device it is showing :

This device cannot start (code 10)

{Operation Failed}
The requested operation was unsuccessful.

If anyone knows how to fix the problem, please help me

thanks in advance

Hi:

The IDT audio driver (notebook speakers) appears to be working fine.

The problem is probably with the Intel graphics driver which  controls the HDMI audio.

My recommendation would be to install the latest Intel graphics driver from the link below and see if that fixes the problem.

Hi,

I have this exact same issue, except instaling the intel drivers from the link has not worked.

I have installed the most recent drivers from the HP website and the Intel website, but sound will still not work over HDMI.

Are you able to offer any help please?

The errors I am getting are exactly the same as the ones in this post.

Thanks in advance,

Thanks.. this did the job for me. I actually had to roll back the graphics driver to a prior version. I noticed that it is bundled with another audio driver. Once I did that the IDT High Definition Audio Driver installed properly and is working again.

much appreciated !
