Troubles playing 5.1 through my 5850 via HDMI directly to the receiver

post #1 of 19
Thread Starter 
New Problem:
Can't seem to get 5.1 audio through the HDMI from my 5850. Any input would be greatly appreciated.

More info on page 2 of the entire audio set-up.











I have a pioneer 520 amp. They are currently connected to the auzentech forte. It looks like my sound card can only put out DTS? I know my amp supports newer formats of DTS and wondering how I could use them?

Cheers on for any input or insight.

Also, somewhat off-topic. How with 5.1 surround being generated? It is as if I'm only getting 2 channel (the SPDIF only gives the option for 2 channels, 96K, 24-bit) with the normal sound card setting forcing me to use 48K so I can use the DTS effects. Kinda confused on how this is suppose to be set up? Also, even under 'window speaker setting' the surround is working perfectly. Anyways, how do I get the most out of these products? I'm happy with them, but would like to see what else they can do 8D

Your HIS 5850 supports 8 Channel Linear PCM, Dolby True-HD, and DTS-Master.

HD Audio codecs are locked to one format: HDMI.

And there's no need to mess around with sampling rates in files. It does nothing useful.

Oh. Does the forte not do it? Does those make it sound better? Awwwwh, was my forte a bad purchase when my videocard could do better? :\\ I get attached to my hardware. I don't know what to do with it if I switch to the GPU to do it. Would that hinder performance as well for the card itself?

I did some research and coaxial doesn't have the bandwidth to output the requirements for DTS-HD and whatnot. Would using the GPU be better? Like the difference between night and day?

The formats are only used during Blu-Ray or HD-DVD playback.

I can't say it's been night and day, in fact I've never bothered comparing them in the first place. I think it's more of a "keeping up with the cutting edge" sort of thing, just like people keep upgrading hardware when they don't really need to. It's just an itch that needs to be scratched sometimes.

Also, most 5 channel HD Audio tracks run at under 4MBps. This is basically CD bit-rate. Up to 37MBps (or roughly 8 to 9 times the bit-rate of CD quality) is usable for audio. So really, while the bandwidth is available, no one has really bothered to use much of it.

I'll give it a shot. HDMI 1.4 cables are on sale near where I live for about 9.99. I'm going to pick one up and try it out. I could also use the sound card as a spare for skype calls and whatnot. Furthermore a headphone amp.

Thanks for the input.

Alright I got an HDMI cable and have it set up. However it is not playing back in DTS HD? I have the options of Dolby Digital Prologic / PLII and DTS Neo 6. Any ideas on how to force DTS HD?

Edit: Alright, now I only have the option for PCM?

Is your source putting out DTSHD? Just because the card can output that format doesn't mean it's going to apply to an AVI file that only contains a low bitrate 2 channel audio track.
Have you tried a BluRay disc yet?

Not yet, I don't have a bluray player on the PC. Which setting is best? I only could select PCM right now, but the moment it uses a better encoder it would auto switch to that format correct?

You need bluray software like arcsoft total threater to either bitstream or decode HD codes.
