1. Does anyone know when the first HDMI compatible sound card will be released?


2. Why no one advertises the obvious:


That we can output ALL MULTICHANNEL DIGITAL AUDIO formats -including games- digitally -no analogue degredation- IF the sound card has the ability to decode them to Multi Channel Linear PCM!!! Every sound card already does that via SP/DIF for all stereo (2 channel) sources!

The only thing we need afterwards is an external HDMI compatible receiver and ONE HDMI cable!!!


HELP get the marketeers out of the hardware companies GIVE US WHAT WE ALL WANT and better carpet bomb Creative!!!!!!!!!!!!

My/Our frustration over the lack of LOGIC at hardware companies regarding AV connectivity should not be simply swallowed. We need HDMI audio connectivity. No more cable web nightmares...

I intend this to become a petition! So just add your comment or a simple emtpy post if you you want to sign my petiton.

It would indeed be a welcome thing. HDMI 1.3 at that. It's going to be interesting to see how they marry "Deep Color" video and the HD audio formats though...


It may be necessary for someone to put out an "uber" video or sound or combo card that does it all. the Radeon 2050XTX/CMedia or nVidia 9900GTX/XFi or some such may be necessary to actually pull it off...


All I can say is the sooner the better if Microsoft really wants to get the most out of Vista and the HTPC/Home Server is really supposed to come into its own this year.

Nvidia already has some experience in making audio chips so they may be the first the release a HDMI audio/graphics card. Of course the only problem would be that it would likely be the top end card only which are cooling nightmares if you want to run a quiet PC also.

We are looking to include HDMI 1.3 ports in our up-coming products, but it may not make sense in our case. The annual license fee is something like $15,000 and that is just the start. It's probably a drop in the bucket to the large CE manufacturers, but we are not a large manufacturer.

Not a discrete solution, but the Bearlake G+ chipset coming later this year supposedly will have built-in HDCP and audio codec built into the Southbridge, fed back into the Northbridge (where it can go out as HDMI). It's a weird-looking solution, and obviously it doesn't help people looking to keep their current setup, but I just wanted to put it out there.

No question in my mind that multi-channel PCM is dearly needed in the HTPC space. What I'm wondering is how they would implement this without "sound card" and "video card" all-in-one. I think the first implementation you'll see is motherboard integrated. The comment above about nVidia being first makes sense, but I don't know if it's on their roadmap.

THe New X_meridian has a add on expansion board that conatins a DIN plug that has 8 channel discrete PCM @24/192Khz output. Quite a few people were thinking this may be able to be modified into a HDMI solution or maybe that is the companies idea..just wanted to share that info.

Question of the day would be, what is the quality like? The sound on past Intel boards has been really poor IMO.

We do not need HDMI 1.3 sound card. Even HDMI 1.1 is already able to transfer LPCM 7.1 audio but not all HDMI Receivers can handle it as audio (they just pass through video). ALL the new 1.2 HDMI and onwards receivers do at least 5.1 LPCM some do 7.1 too!


We do not need a merged Sound - GPU card if we just use two HDMI cables (audio - video). So for NOW two HDMI cables would suffice for PERFECT audio and video quality transmission.


Even if you opt for the single audio-video HDMI cable, the only thing that must be addressed is an internal HDMI audio-video stream merger solution which can reside in either the sound card or the GPU. Plus synchronization issues are much more easily solved by a PC software player than ANY other method including such functionality in the HDMI 1.3 spec!


PS If you get the digital audio signal out of the PC you stop caring about the intergrated sound quality you can use the best audio quality -equipment wise- that matches your wallet!

We do need them on the same cable. Alot of people already have a couple devices routed through their reciever, having them on seperate cables would create issues for anyone with only one HDMI in port and multiple HDMI devices.

I agree, I have no desire for audio and video on a single cable because I want to route audio and video to separate components. HDMI video straight to the display, and HDMI audio (7.1 LPCM) to the pre/pro.


Maybe some would prefer to run video through the pre/pro or receiver as well, but for my setup that would mean giving up flexibility. By having video sources run direct to the display, I can have per-input video settings (something I could not have with just one cable running from the pre/pro to the display).

I am speaking of a right here right now solution. The typical scenario would be:

I connect my PJ,TV, etc with the HDMI video cable to the PC GPU, I connect my receiver with the audio HDMI cable to my HDMI compatible sound card. The later is nowhere to be seen...

You may be right about this reputation-- I've heard that about older boards, but people have seemed pleased with newer stuff-- but are you speaking of analog or SPDIF? Analog audio on a motherboard runs victim to a tremendously noisy environment and potentially cheap DACs, but digital?

HDCP or not I see no reason why sound and video have to be on the same cable. And is HDCP even an issue for the audio? If so there's no reason the sound card can be HDCP compliant. Call me crazy but I doubt we're going to see a video card anytime soon that can accept 7.1 LPCM over HDMI and combine it with the video signal. A combo video/sound card would be far more likely IMHO.

The same logic can be reversed, so you do everything sound card centric (its cheaper and more easily upgradeable than a high end GPU)!


But that is not the main point! HDMI is not just about HDCP content, it can solve, as a transmission bus, ALL CURRENT Multi Channel Audio output demands, digital & losslessly! There are no HDCP games, all of them output LPCM Multichannel at some stage inside the sound card before the signal hits the sound card's DACs. If sound card vendors would give us the ability to output that Multichannel LPCM signal via the HDMI output we would need no analogue connections to an external receiver/amp. This applies to any source including multi channel WMA and all future unDRMed formats etc!!!
