Recommended ATI driver for HDMI probs?

Excellent question; I've just been doing the updates as ATI comes out with them - but using either Realtek's or ATI's no matter what version I've had issues after issues. The issues do change with the versions, so just when I think they might have it nailed, something else starts...
Anyway, not real good answer from me, just saying...good question! Searching the net and getting an answer from 2009 dealing with Win7RCs doesn't seem to help...

I'm having no trouble with the latest 11.8 Catalyst drivers (including the ATI/AMD HDMI driver).

I used to use Realtek until I had bitstreaming issues with it, now with ATI's everything has been working for me.

However, I did have to disable Windows Media Center's menu sounds, so if you're using that, keep that in mind.

I had trouble with mine too (HD4250) until I installed an EDID overide.

It's easier to make one than it sounds in the EDID overide thread.

anything from NVIDIA with a card to go with it.

I am using 10.7. I have tried most of the 11.x with no luck fixing my wake from sleep issue. At least 10.7 does not have other issues (remembers overscan settings, etc).

Actually I still have the issue with 10.7, but got tired of trying older drivers to fix the issue. My issue is no sound after waking from sleep, I have to reboot each time to get sound back.

good luck...

just use the latest drivers from amd.

I recommend installing a cheap ati 5450. Connect the dvi output to your tv and the hdmi output to your avr. Set you tv as main display 1, avr as display 2, and extend your desktop to the avr.

I did this and I can now switch inputs on my tv and avr without having to restart anything.

It's a hit and miss with ATI cards. I had to dump my ATI 6450 for a GT440 to get this working properly.

I just had the last battle with the remmants of the last ATI driver I will ever install. I have a nice collection of Radeon cards though.

Even though, the driver had been uninstalled through the control panel and Drive Sweeper had been run fragment were still there and somehow keeping SP1 from installing. I had to jump through some hoops to get SP1 installed. All is good now. Service Pack 1 actually made me do a Windows Upgrade. Long drawn out deal, because all the patches had to be reinstalled and then SP1 and more patches. Apps and other stuff came through the upgrade instact.

I did not want to do a clean install as I would have lost a PD DVD 10 install that the PID Key was OEM from an Amazon deal and it won't install again. Cyberlink's attitude is that if I didn't get it from them tough.. receipts and original media don't mean anything to them. Gotta love Cyberlink, gotta love ATI/AMD drivers.

I was able to accomplish this with a 5450 and a 4550. Bitstreaming only works on the 5450 so I paired the 4550 with an hdav 1.3.

Well, with 11.8's and 5600, Realtek HD Ati hdmi that comes with it. I'm having a problem whereby it's stereo(2 speaker output) to my recv'r if it's not powered on prior to starting up my pc. If I turn on my recv'r 1st then the pc the ATi hdmi shows 5.1 etc. as an option.

You should not install any Realtek hdmi drivers, only hdmi drivers included with Catalyst for proper bitstreaming.

Well, this is kind of a bump, but I have recently found that I don't understand the AMD drivers as well as I thought I did, so maybe someone could help out with some enlightenment.

My HTPC is 3+ year old technology, running XP SP3. Onboard sound is Realtek something or other with no S/PDIF output. Graphics card is an ATI HD-4670, one of the first to do audio via the HDMI port. Back when I performed the original install, I used whatever version of Catalyst CC was current at the time, and also found that I needed an additional HDMI audio driver (ie, file 9-9_xp32-64_hdmiaudio.exe, version 9.9). So this provides me me with two audio output devices, ATI for digital and Realtek for analogue.

Fast forward three years and I upgrade to Catalyst Software Suite 12.3, which allegedly includes an AMD HDMI audio driver according to the official website. Install new drivers over the top of old drivers, expecting to see that the HDMI audio driver version is greater. Nope, it's still at late '09. OK, so we uninstall that driver, locate that area of the Catalyst distribution that seems concerned with XP audio drivers, and install the package again. After a restart and detection of new audio devices, we seem to be back to driver version 9.9. WTF?

Or is it that the Catalyst distribution doesn't really include HDMI audio drivers as advertised? For example, a bit of digging around suggests the existence of file 11-12_xp32-64_hdmiaudio.exe on some anonymous driver site, not that I can find it on AMD's site. I know recent versions of CCC are claimed to be backwards-compatible with my old graphics card, but there don't seem to be any guarantees about this particular audio driver. Can anyone put me in the picture here?

Well here's the answer, mainly for posterity's sake. Uninstalling the original driver via device manager doesn't work completely, because it leaves the driver file ATIHdmi.sys in Windows\\system 32\\drivers. But for that matter, installing the new driver doesn't work either, because it silently fails to add AtihdXP3.sys to that directory. On restart, the machine detects the audio device, then grabs whatever driver file it can from that directory to re-establish itself.

The driver in the 12-3*ccc distribution is slightly ahead of that in the 11-12*hdmiaudio distribution, ie, 5.18.0.5511 versus 5.18.0.5510.
