HDMI Audio (what to do when it fails!)

[chazzy2501]

Urgh, I've run into this a few times now and I have only found one solution...Total reinstall of windows! There has to be a better way...

 

What happens... The laptop will see and use the external display (often seen as digital Television) but this won't appear in the audio device manager. It's not a disabled device either..

 

In device manager it's doesn't appear as a hidden device.

 

I've tried... Uninstalling the driver (fully including the audio) and reinstalling after a reset.

 

Uninstalling the external monitors from Device Manager.

 

updated with the latest (and some older versions) of Intel's Graphics Drivers (includes the HDMI audio).

 

The it will not appear at all (as an audio device) it's like it doesn't exist.

 

This occurred today as when a teacher first plugged in the hdmi cable windows began installing the audio device but the teacher cancelled the install! (?why?)

 

Ideas? some registry file with devices in it?

You will have 2 audio drivers one will be onboard the other will be when you connect the HDMI cable, I have found out its an intel HD audio driver which works well with dell and Toshiba laptops.

 

Your will have to download and extract the files and navigate to the HDAudio folder and select the correct sys file.

 

It may come up with a warning message that it could be incompatible but just click okay and it will install the driver for you.

 

I have 100 screen across 8 primary schools and had this issue with most laptops.

 

Hope this method works for you

Just an update, Trying a different Displayport to HDMI adapter works fine with the Epson Projector. I don't know why but what the hey, I'm thinking it's an HDMI protocol or something, as the other adapter works on everything but the Epson projector it's not broken. I'll be buying the second type (adaptor) from now on.
