I mean COME ON this must be like the first time PC hardware is actually behind with something that has to do with "digital"

I just want uncompressed sound via HDMI, can't be too hard can it? Not that optical loopback thingy some gfx cards offer ... I want the real thing! Fed up with DTS Interactive / DD live!

EDIT: Hmm shame I didn't use Google Apparantly Auzentech already has a prototype extension for the Prelude soundcard:

This is exactly what I need, if it's able to output everything as LPCM that is (and not just via Powerdvd or summit)[thumbup]

Uncompressed sound? How are you going to achieve that?

LPCM is what I meant by uncompressed [thumbup]

So I can finally play blurays / hddvds on my pc with full potential, and don't have to worry about surround sound in games being compressed (by for example DDlive) when using a digital connection (hdmi in this case)

aren't video cards with HDMI meant to act as the HDMI throughput?

The soundcard will do all the processing, but then the digital signal is sent from the soundcard to the video card then out through the HDMI of the video card. That way the audio and video processing are in sync.

I could be wrong.

Yep that's how it's working for now, but it currently uses an optical cable to pass its digital signal to the video card, which can only deliver compressed (DD / DTS) surround sound

That's why this new extension is better, it does the exact opposite: Takes the video signal and adds 5.1 LPCM to it [thumbup]

Yeah, it will avoid the current downsampling (-> 16bit/48kHz) performed by software players!

Btw, LPCM doesn't sound any better than compressed lossless DD TrueHD and DTS HD Master.

Lossless > LPCM -> More space for higher quality video.

Yeah I know was just trying to explain it as simply as possible.

Anyway the soundcards nowadays aren't capable of encoding either of those compressed streams "Live", so adding a HDMI port without adding 5.1 LPCM support would be useless And thus the usability of those 2 streams becomes pretty much 0 for a soundcard. It would need alot more processing power on the soundcard (= money) to even decode it

It was my impression that many of the ATI cards (e.g. HD2600) had built in sound chips that did proper HDMI audio out (without the optical pass through)?

I think with the HD2x00's they take the sound from whatever soundcard you are using via the PCI/e bus (magic?!) and combine it with the video output, AFAIK whatever you feed into them is downsampled to 16/48.

why not use the analogue output?... this way you dont need to encode into DD or DTS
