Radeon HD5450 Audio over HDMI

My mothboard says in sounds of control panel , Windows XP, AT rear audio output or something to this nature.

The machine is an HP with what I would call Business Audio with a puny speaker somewhere in the case itself.

We added this new graphics card to do HDMI to a TV and VGA up to monitor.  To my surprise, the HDMI cable to the TV is pushing audio as well and is dominating the built in audio.

This would be okay but we really want sound in both locations and for the VGA card to but out.

We bought a mini-pin splitter and ran that to TV audio input and hoped to use that as an audio split to the speakers of the desktop.
OR
If I need to , I can go get a cheap audio card PCI if this will force windows control panel sounds to see it and then we could ????split with mini-pin???? to both sources seamlessly.

Any help is greatly appreciated.  I have googl'ed for where in the Catalyst Control center to turn off Audio over HDMI.

They suggest uninstalling all software and downloading the legacy 10.2 driver package.   I have done this but somehow the HDMI over Audio still worked.   I suppose maybe the uninstaller left enough inf remnants to still run the HDMI over audio even after uninstall.

Hi,

If you set your default audio device to be the speakers (probably Realtek) then sound would be routed to speakers rather than HDMI. You may also find that some software (e.g. PowerDVD) allows you to send sound to HDMI even though your default audio device is different.

Can you explain a little more clearly what you want? I believe you want to send audio to 2 rooms and use both VGA and HDMI for sending video?

Hi,

I believe that J RIver Media Center allows you to send audio to 2 separate sound cards - would this help?

Hi,

If you have a realtek audio card, you can use the following registry 'tweak' to re-map front audio to all of the jacks - i..e you can run 2 separate cables to each room and get the same audio in both:

I need the Audio over HDMI disabled.   The card has a built in over ride that zaps all other Control panel settings and makes itself primary regardlless.

I think mt uninstall was only half complete.  I need to get the drivers for the HDMI over audio off.  It appears the uninstall for the software leaves these down in system 32 and upon reboot , windows finds them again and we are back at same proboem.

We have an onboard Audio but it seems totally dead even though selected in Ctrl Panel.

How can I get a clean install of the drivers for VGA card and then I already know how to force the VGA portion only to load.

If onboard speaker port comes back to life , I then can use my mini-pin splitter to get audio to both sources.

I just hope the TV doesnt fight me.

Hi,

Have you tried disabling the ATI audio driver in Device Manager?

Hi,

Also check you BIOS and set the onboard audio to Enable rather than Auto which it might be set to.

Let me check these things and get back.  Since we are talking BIOS, I need to go over and lay hands on the machine.

The BIOS was key to what was a long process of amnually removing the card and then tricking windows one step at a time.  Also had to manually delete a ton of ATI files from the registry
