For anyone who has been able to get bitstreamed audio from a 6450, I am impressed

After a week of researching, troubleshooting, uninstalling/reinstalling various drivers...I give up. AMD has defeated me.

I thought this 6450 was going to be a great htpc card, and initial indications were that it was going to be perfect. I have an older core i3, and wanted to add 3D capability to my htpc. When I first wiped all the existing drivers and installed the card, everything was going well. I got 3D going, and performance looked solid in playing back full quality blu-ray iso files...and then came the part of trying to bitstream DTS Master Audio or Dolby TrueHD. I found various threads on AVSforum and across the internet on changing certain settings, rolling back to previous Catalyst drivers, installing a Realtek hd audio driver, trying to recognize a specific EDID...I tried it all, and did it thoroughly (at least as thoroughly as possible, going to safe boot and wiping drivers, including sweeping for all AMD driver files, before installing a new version).

Finally, last night I gave up, wiped all the AMD drivers, and re-installed the Intel graphics and hdmi audio. Works beautifully, bitstreams MA and TrueHD like a charm. 3D will have to be through my blu-ray player, I'm leaving the HTPC like it is now.

I still think this is a great little card for many people - silent (fanless), fairly cool, good video performance, low profile, and cheap ($35). But for anyone who got bitstream going on it...you're a better man than I am.

I've always wanted a legit HTPC, but have not found any media presentation app+remote setups that make any sense to me, and man are they expensive.

Streaming to my PS3 slims is much more elegant, my library data is consolidated onto one machine and can stream to anywhere in the house and I don't have any issues with the various audio codecs..... of course I would not be one to fight to the death over DTS-HD either. you could encode it to AC3 and I would never hear a difference. I just picked up a third ps3 slim off craigslist for $100. They are really great for playback, in that they work like an appliance so my gf or some guest can figure it out in a snap. no configuration on the client side whatsoever.
 
I had the opposite experience - with the core i3 and integrated gpu, and using WMC (vista) with media browser, the situation has been phenomenal.

On the other hand, I have not enjoyed trying to stream to PS3 (mostly because I have stubbornly kept trying to find something to transcode .iso files). Even when I finally broke down and re-encoded a batch of movies to mkv, I still find the PS3 to be anything but elegant. I just don't like the interface.

So far, the best combination of presentation/reliability/reduced setup time is the Media Center/Media Browser combination on a htpc. Once you get it set up, just rip to a folder as an .iso, and you're off, and interface is far superior to any other devices like a PS3 or O!play or HD Live.

Only recently have I had issues, when I tried to add a graphics card for 3D playback. If I were starting from scratch, I'd just get the Sandy Bridge and never think about separate graphics again.
 
ah, I can see how .iso streaming might throw a wrench in the engine. all of my stuff is x264 so there is no transcoding or anything like that being done.

I have tried serving media with WMC via the xbox and ran into playback issues on my high-bitrate stuff. I admit the interface is prettier. I can imagine WMC working great from a local disk, but I have too many display devices so I have to stick to a client-server model and can't bother with maintaining duplicate libraries.

I have also read that the IVB GPU should support stereo 3D. So hopefully you can ditch the radeon and achieve what you want with a 22nm i3.
 
Took me forever to get it working on a HD5770. Tried numerous versions of ffdshow before I finally found one that worked. Even then I still often loose proper audio streaming where it resorts to stereo output only. A restart will usually resolve the issue.
