Dear all:
I have an Aspire E5-574G.
I am having problems with Audio, only when connecting via HDMI to my Samsung TV + Sound Bar.
I have been using Acer Care to install new drivers and whatever Windows Updated suggested.
I have got a brand new high speed HDMI cable and I know it is not it,as the same cable on the same port with other computer works fine.
I am assuming that the HDMI port is hard-connected to the Intel graphics card (and not the nVidia, I have two cards).
Therefore I am checking the Intel HD Graphics 520 drivers currently installed (via Device Manager) with what the Acer support site has and I can see my current ones are newer.
Currently installed

But when I download the .zip file and open the install_readme.txt file it states:

I am reluctant to install such an old driver.
I have validated already the sound effects are turned off from HD Audio Manager.
My sample rate is 48000 Hz and sample rate 24 bit, the highest one.
It fails with Spotify / YouTube on any web browser and any music / audio intermittently.
Device Manager does not detect any new driver to update, neither Windows Update suggests anything. The Intel automatic driver validator states that this video driver is custom Acer and refuses to suggest any new driver.
Thanks.

It no longer matters what computer manufacturer's specific driver is anymore.

The fact that you DON'T tell people that the old driver has unpatched security vulnerabilities BEFORE you tell them to install them is irresponsible.
You are not giving them an informed choice.
Restart your computer.
Then try to install the new Intel DCH driver over the generic driver.
