ATI 5870 and HDMI out.....

conuk · 15 Apr 2011 at 23:00

if I use the HDMI connector on my Sapphire card to my tv... will it carry sound as well?

I realise the DVI to HDMI cables wont......

Certainly will.

conuk · 15 Apr 2011 at 23:34

cheers mate.

Nee bother - It's better these days too, just plug and play

hmmmm finally got this up and running.

Have it setup so that my monitor clones onto the TV - (I have a logitech mini Di Novo to control XBMC)

when going to change over my sound settings in hardware playback - AMD HDMI output is shown but states not plugged in.

Any ideas how to enable the sound ?
Otherwise sound comes from my Logitech speakers at the other side of the rooom....

In the Control Panel under Sound you need to set your default audio device to ATI HD Audio (it's called something like that).

You need to enable ATI HD Audio, install the ATI HD audio drivers if you haven't already and set that as your default audio device.

That's the only way to get audio carried through the HDMI lead - it comes out of your graphics card not your Asus Xonar or the motherboard's onboard audio.

thanks surveyor.

arent they already included in the 11.3 drivers ?
It shows up in device manager...... just wont let me enable the sound output.
am running windows 7 64 bit as well if that helps.

have tried just using the HDTV as screen instead of Monitor and TV - audio is still greyed out.

When you right click on ATI HD audio in the device manager you don't have the option to enable it?

conuk · 7 May 2011 at 20:52

nope.

only disable.

set as default is greyed out as is test - can goto properties.. reinstall driver ... have uninstalled restarted windows ... etc etc ... same issue.

thanks for your help.

hmmm just noticed it doesnt say ATI HDMI now... either way it is still greyed out.

maybe uninstall ATI driver suite and reinstall ?

Surveyor · 7 May 2011 at 21:00

Try installing the latest drivers from AMD.

I'm sure that when I do that it automatically enables the ATI HD audio.

Download and run the full Catalyst Suite and when it gives you the option to install or uninstall then uninstall everything. Restart and then do a custom install and you can ensure the audio drivers are selected.

Select your drivers from here:

Try disabling you other audio devices.

They can always be enabled again.

I have this problem with my 4870 and my TV. Easy fix is to reboot your pc with the tv turned on.

It seems to have difficulty recognizing it is plugged in at times other than post.

conuk · 7 May 2011 at 21:49

disabled the others...... rebooted with TV on .... off .... no difference.
