I have just installed the above mentioned grapics card. I have video but no audio via the HDMI. The only audio I do get is through the onboard audio. I am running windows 7 ultimate
Any help greatly appreciated

You need to set the HDMI audio device as the default audio device in the sound applet in control panel.

Couple of other things to check:

1. Make sure if you have any Realtek audio drivers, uninstall them.
2. Re-install the latest Catalyst drivers from ATI
3. Ensure the ATI HDMI audio driver is set as the default (Playback Devices --> Properties)
4. Make sure the "levels" for this card are set to 100
5. Open Windows volume mixer while all your apps are running and make sure all the audio levels are set to maximum
6. If you have audio issues with bistream (TrueHD, DTS-Master HD) from apps like TotalMedia Theatre, install and configure ReClock.

>Reclock download link.

Make sure you read the ReClock Readme file to learn how to configure it correctly so that it actually runs and does stuff rather than sit there and not do anything!

>Fixing bistream problems with ReClock link.

Lastly, if you never want to use onboard audio again, disable that device in Device Manager. Or better yet, disable it in the BIOS so it doesn't even appear in Windows.

Thanks kaldeck.

Does anyone know if the Radeon HD 5450 is compatible with a 5yr old ASUS P5GDC motherboard? We think this may be why we are not getting any sound as we put the old card back in and it was picked up but the new card is not being picked up. I think we may need a new motherboard. Can anyone assist and let us know what requirements/type of motherboard, we should need, if this is the problem?

I don't know anything much about this card, but when I had the problem of no audio through HDMI with an NVIDIA card,, it was because the installer had not run an audio jumper cable from the mainboard to the video card, and without it the HDMI would not carry audio. It appears that there are some who believe that audio through the HDMI is not neccessary if you can run audio out of the computer elsewhere.

Maybe that is part of the problem.

I run the same card on an Asus M2N-DH which is also about 5 years old. The HDMI audio works perfectly although I do not use it as the sony LCD I have won't let me pass it through to my amp.:(

I'm running a 5450 on a 4-5 year old Gigabyte UD3 mobo, with 2 gb ram, E6600 cpu. Would have to check at home for exact model and revision number.

I previously had a 4550 in there, but took the chance to upgrade to a 5450 to get HD audio since this machine is plugged into a HD capable 7.1 amp. I've then put the 4550 in a second htpc that will only ever drive a stereo tv, or low end amp.

At first I just took the 4550 out, put in the 5450 and rebooted, and I had video but stuttery sound on first boot up. No surprise really, being lazy. So I fully uninstalled all Realtek and ati catalyst drivers. There was a realtek Ati HDMI driver on there from the 4550 that I took out.

Then reinstalled latest ATi catalyst drivers (10.7 from memory). This put an ATi HDMI device on there, so I haven't put any realtek drivers on so far.

Selected ATi HDMI audio device out as default audio device and that's it, getting full video and sound, including DTS-HD MA, etc from bluray images via total media theatre plug in MC7.

So basically I followed Kaldek's recipe as above, nice summary. Although I didn't need to do step 6 with the reclock program. I will check my levels though, as some audio is very quiet relative to (some) recorded tv.

Oh, there was a total media theatre update around this time as well, so I did that and its fully up to date with current version.

I didn't have to physically connect anything to the video card inside the PC case, just HDMI cable straight into the back of the video card.

Quite happy to see the DTS MA etc come up on amp first time too, most painless upgrade ever! :)
