This card is the real deal for HDMI out of your computer. It is precisely what I hoped: An X-Fi hooked to HDMI. It comes with the X-Fi software as with any other card. Only thing notable missing is the THX console. Of course the function of the THX console was to set things like speaker delays and levels, which any HDMI receiver will be doing for you so it isn't needed.

All you have to do is turn on "Play Audio from Speakers through HDMI" In Settings -> HDMI -> XFi Audio Settings and it just works. So long as you make sure the encoders are off (it comes with DTS and DDL encoders for whatever reason) you'll get 24-bit 96kHz LPCM out to the card from any applicaiton you like, in any mode you like.

In Audio Creation mode, it also works just fine, including bitmatched playback. If you turn that on, it'll output the frequency as per the clock setting in the control panel, rather than 96kHz (in other modes it resamples everything to 96kHz). Works fine with ASIO too.

Games, including OpenAL, work just like you'd expect. It's mic input works just just fine so my NC-8 works with TeamSpeak just like it did with the Elite Pro.

Speaker settings work fine and it only outputs per the configuration you've set. So if you only have 5.1 speakers, you set it to 5.1 and it'll send a 5.1 stream to the receiver, not a 7.1 stream. My receiver picks up all the streams properly and maps them to the 5.1 I have as per my settings.

Also, despite what it says in the manual, the volume control works fine in the console. I can't see why you'd want it with a receiver, but it works.

I haven't messed with any bitstreaming yet since I don't really do movies, but of course since that is practically the only thing covered in any other review I think you can assume it works fine.

It does require video input to function, I'm using a fake second monitor from my video card for now since I have a 1920x1200 monitor. I think I'll buy a cheap HDMI DVD player to supply it instead at some point, or an HDMI signal generator if I can get one cheap.

So far I've seen no problems with it. The stream from it has been clean and error free. It is continous too, so audio plays right away. Some HDMI devices, like my Radeon, stop the audio stream when sound stops. However because of various things, it takes a few seconds to establish a new stream meaning when it restarts, there's a silent period that is real annoying. No such problems here. It works just like if you had an analouge connection.

Sound quality is great, of course. It nearly fixed my noise problem. With DTS Interactive out of the Elite Pro, there was a slight audible hiss when the receiver was set to full reference levels. Not all that bad, but it still bothered me. It is now totally inaudible on the front speakers, and very nearly so on the front and rear speakers, you pretty much have to get up form the seat and get closer to them to hear it. That's just because the front channels have a better dedicated amp, and the rest use the receiver. Before, all channels had a good deal of noise from the bitstream, probalby 15dB more than now.

Also, I think it gives slightly better spatial imaging, particular with regards to front and back, than the DTS stream. I can't say for sure since I can't figure out how to do a blind test, but I did seem to notice better definition for surround effects from DVD-A sources. Would makes sense since channel coupling is one of the ways DTS reduces bandwidth, and surround is given less weight. However, it also could be in my head since it is not a valid blind test.

In conclusion, this card is the real deal for receiver based gaming. I don't know that I'd say you need to run out and upgrade if you already have an X-Fi that does DTS out to your gear, this isn't night and day, but if you are looking at a new setup, I'd get one. Also I'd consider getting one if you have a true high end setup that can do full reference levels as you WILL get some audible noise from DTSI on that, when you turn it up.
 
My receiver is a Denon AVR-3808CI. It is supplemented by a Rotel RB-1050 to drive the front channels (mostly because I already owned the amp when I got it). The front speakers are SVS MTS-01 towers. The centre channel is the matching MCS-01 centre. The rears are currently B&W 601S2 bookshelf speakers, though I plan on replacing them with the SVS MBS-01 speakers at some point. The sub is an SVS 20-39 PC+ the predecessor to the PC12-Plus.

This is adjustable right? Because I'd rather play my music at 44.1khz.

Speaker settings work fine and it only outputs per the configuration you've set. So if you only have 5.1 speakers, you set it to 5.1 and it'll send a 5.1 stream to the receiver, not a 7.1 stream. My receiver picks up all the streams properly and maps them to the 5.1 I have as per my settings.
Ok, good that you point this out. Is there a way to know how many channels is the source? I ask this because that was a big problem with the Asus Xonar HDAV1.3.

Lets say that I have a 7.1 setup, and I configure it to 7.1, but then I decide to play a game or video that only has 2.0/5.1, the remaining channels will remain empty. I had to either put my ear in each speaker to determine if the source was 2.0/5.1/7.1, and then adjust it, so I was able to do upmixing in my receiver again. Or, I was forced to use the upmixing already included. However, it never sound right., or at least not as good as when the receiver itself was doing the upmixing. Also, X-Fi cards I think don't have ProLogic IIx, but have NEO:6 Instead (meh).

If it doesn't have an option to do it automatically, then let me know, so I can start getting prepared mentally, lol. I think that's the only feature I envy from the PS3, that it just changes channels and frequencies automatically. I know that a PC is more complicated, because it can multitask much more, but at least make it automatic until there is a mix of audio streams, AND THEN make it whatever It set it up to.

It does require video input to function, I'm using a fake second monitor from my video card for now since I have a 1920x1200 monitor. I think I'll buy a cheap HDMI DVD player to supply it instead at some point, or an HDMI signal generator if I can get one cheap.
Does you monitor have a 1920x1080 mode? If so, can you test something for me?
When you hook the the video using the soundcard, as oppose to directly to the monitor, does the colors change, or is there any delay?

I ask this, because the HDAV1.3 doesn't have any delays, but it does alters the colors. I know it wasn't the HDMI connection, because I've used DVI-HDMI cables before, and used my receiver to pass the video as well. I've also calibrated both DVI and HDMI inputs so they look identical. However, video coming from the HDAV1.3 looked different, they were too intense (fake), and that bothered me.

So far I've seen no problems with it. The stream from it has been clean and error free. It is continous too, so audio plays right away. Some HDMI devices, like my Radeon, stop the audio stream when sound stops.

NICE, that is perfect. I hated that from the HDAV1.3, and still hate it from the PS3. I sometimes failed to hear error messages because of that delay. That is good news.

Only in Audio Creating mode. There you can turn on bit matched playback in which case the output is locked to the clock setting in the control panel, which is set to whatever the software addressing it asks for. In other modes, upsampling is automatic. As a practical matter, anything sent through MME, DS, or XAudio will be upsampled by Windows 7 if the X-Fi doesn't.

So you need to be in Audio Creation mode, and use an app that addresses the card via ASIO or WDM/KS.

Do note that I seriously doubt you can hear the difference as the X-Fi's resampling engine is top notch.


Ok, good that you point this out. Is there a way to know how many channels is the source? I ask this because that was a big problem with the Asus Xonar HDAV1.3.

No, that's a Windows thing. Games and such should use whatever number of channels you have. They don't address sound to a channel, they specify the direction it should pay at to DS or OpenAL, and it then positioned to the speakers by the software/hardware.

It might be possible to get something to change the speaker config in Windows, but I doubt it.

My monitor does support 1920x1080, but I can't really give you a useful answer to this question. The monitor is a professional NEC monitor, and is colour calibrated. That is a per-input thing, so the colours look different anyhow, simply because DVI 1 is calibrated and DVI-2 is not. The calibration software can't access the monitor through the receiver with the commands it needs, so calibrating it isn't really an option.

Also any delay measurements would be problematic since I don't have gear to measure it.

One thing to check is to make sure it isn't your receiver doing the colour changes. Many receivers clamp the signal to 15-236 per the NTSC spec rather than the full 0-255. You have to go change that. Also receivers frequently have controls for hue, saturation and so on.

That said, their information on the unit leads me to believe it makes no changes to the video at all. It simply intercepts the audio stream and replaces it (that can also be defeated with jumpers though I don't see why).

Hmm, that sounds weird, that you can't change the sample rate in Entertainment mode.
I guess that's no problem, I can still use my onboard sound to send music to my receiver as 2.0 PCM at 44.1khz. Changing playback devices in Windows 7 is fairly easy/quick. Or I can continue using a dedicated software for music alone, and just set it up to output using my onboard sound at 44.1khz via Optical automatically.

No, that's a Windows thing. Games and such should use whatever number of channels you have. They don't address sound to a channel, they specify the direction it should pay at to DS or OpenAL, and it then positioned to the speakers by the software/hardware.

Yeah, I kinda figured. Maybe the next version of Windows gets another improvement in the sound engine to make such things possible.
Yeah, games are not a problems, the real problem is movie trailers from the Apple website. Some of them are 2.0, and others are 5.1, so I have to constantly check.

For example, take the trailers for Terminator Salvation. Trailer 1/2 are 2.0, but trailer 3 is 5.1. It just annoys me that I have to inspect the video every time I have to play it, if I want it to output it correctly. And no, Quicktime won't upmix, even if I set it up to 7.1. It just plays whatever the video was encoded as, and fills the remaining channels with...NOTHING. Besides, QuickTime is terrible. I simple save the videos, and play them back using VLC or MPC-HC.

YouTube videos and stuff don't bother me because I know all of them are 2.0.

Yeah, that's what the description says for the Asus HDAV1.3 as well, but it still messes with the color. I've ran a DVI-HDMI cable to my TV, and also to my receiver, and also DVI-DVI (my tv has DVI port as well) and all times it plays the video fine. Is just when the HDAV1.3 is in the way that things look funky.

I also wanted to ask, how does the 24p play back work? How does it work?
I've read that you can simply change the refresh rate to 24hz in Windows (not possible by default in XP, only on Vista and 7), and it does the job fine.
So, how does the X-FI HT HD make it any easier than it already is? I mean, it they advertise it so much, it better make it automatically, or at least with the click of one button.

Ok, thanks for the answers man. Is just that I've being waiting for that soundcard for a LONG time, back when the rumors started like 2 years ago. I ran desperate and made the wrong choice of buying the Asus HDAV1.3 Deluxe. What a waste of $250 that was. I just want to make sure I don't make the same mistake again, and get burned.
 
I haven't tried any 24p stuff, my monitor doesn't support it. I simply have my ATi card handle all the resampling of the video up to 60fps. Remember that my video is fed separate from the card.

Also I've only given a very cursory try to DVD playback at all. It works, and it can output DD over HDMI, but that is all I've tried. This is not a HTPC, it is a gaming and music creation PC. It just happens to be hooked to a massive sound system because I'm an audio head.
 
Oh and the reason you can't change the sample rate in other modes is simplicity/convenience. Most people have a poor understanding of sample rate and how it works. Also in XP there are some serious consequences to having an app request a low sample rate, and then subsequent apps being resampled to that rate. So they just take the approach to resample everything. The X-Fi processor has a massive bank of circuits to do it. I can resample 512 streams at once, and does so with no audible effects.

Thus they upsample everything to the max rate, and there's no problems.
 
From a features perspective this looks like a pretty nice upgrade from a standard Creative X-Fi card. I was wondering if Creative would release something like this but I guess they're just making money off of licensing their technology to people that actually want to develop the hardware and software for the card.

I'll definitely look into one of these for my next build because it'll be nice using HDMI for 7.1 LPCM gaming. My [X-Fi] optical (music listening) always seems to sound cleaner/brighter than my analog 7.1 (gaming) connections so it would be nice to get a boost in quality for playing games and then not having to switch between sources and just get a straight digital signal for everything.
 
Ya 100% digital is nice. Also tends to solve ground loop problems. My system was plagued with ground loops despite my best efforts to eliminate them. I had got the hum to a pretty low level by snapping the ground pins on my amps (not the safest thing to do) but not gone. However when I got the receiver instead it eliminated all the problems since it was a digital connection from the computer.
 
so what do think this monster will be like when it hits next month?

Looks like it'll probably have rather good analogue quality. In that respect it'll be a replacement for the Elite Pro. Not near as many inputs or outputs, of course.

Of course at this point, I don't know that high quality analogue soundcards are that useful in the consumer arena. My basic feeling is that if you are using computer speakers, get a reasonable soundcard. A midrange one is likely to be much better than your speakers and thus not a problem. If you've got high quality gear, you probably have a receiver and you want to do digital to that thus you want HDMI or S/PDIF. I don't really see much need for high quality analogue out.
 
Any new opinions on this? Newegg reviewers seem to dislike this card.

Same here. But I think the author enjoys it since, undoubtedly, each product has its fans. So, maybe some just encounter the issues which never happen on others.

Just mention some problems I ran into before…Auzentech X-Fi HomeTheater HD often displays false info on both my powerdvd 9 ultra and receiver (Onkyo 905). Besides, driver of this card from Creative is still a kind of buggy as we know, and…not very friendly I think… Sometimes, sound become corrupted and annoying with no reason.

I still think it’s over priced and might have some better choices than this. But…well, if it goes well with you, just choose and stick it.
 
It's high priced for sure. The reason to get this card is if you want an X-Fi chip with HDMI output. Reason for that would be things like hardware OpenAL/EAX out to a receiver. If that's not what you are doing, then there may be better options. There are other, cheaper, HDMI cards if all you are doing is watching movies. Likewise if you aren't buying it for the HDMI output, don't buy it. Auzentech has other X-Fi cards that don't feature HDMI and cost a lot less. The only reason to get this card is because you want X-Fi AND HDMI.

djoye: I wouldn't pay too much attention to Newegg reviews. You have to remember there's no check on the people who review it. They may well not know what the hell they are talking about. In fact, looking at the reviews, that seems to be the case. There are two reviews that whine because it doesn't do 192kHz/24-bit LPCM, only 06kHz/24-bit LPCM. Ok well for one, I really doubt you can hear the difference. Never mind human hearing limits, very few speakers have any response in the 50-100kHz range which is what you are talking about there. However more importantly it never claimed to do LPCM at that rate. If you read the docs, it says 24/96 for everything, 24/192 only as a direct stream from Blu-Ray movies and only in Entertainment mode.

Also another of the reviews is complaining about the problems with old Denon receivers. This was a real problem, and one of the reasons I didn't get one right away. However Auzentech got some old Denon receivers, figured out why there was a problem, and released a firmware update that fixed it. All the current cards have no problem (I have a Denon 3808CI) and the old ones can be updated to have no problem.

I'm always wary of any bad review where the person just couldn't make it work right. Ok while that is possibly a problem with the hardware, it is more likely a problem with the person. I do computer support for a living and all the time we get complaints that something "Just doesn't work, is broken," and so on. Often as not that is not the case, the case is in fact the user can't figure it out and thus decide that means it is broken.

pbentoto: I'm not sure what you mean that it displays false info on your receiver. You realize that the card cannot tell your receiver what to display. The receiver is displaying the info on its own. It is simply showing you the information on the stream it is getting. So, if the receiver says something is Dolby Digital, that's in fact what it is receiving. If you think it should be something else, fine, but the receiver isn't wrong, it isn't displaying "false" information, it means that you need to change the configuration somewhere else.
 
I also have this soundcard. It's connected to a Denon 4308CI receiver and doesn't have any of the handshake issues that were initially reported with this card and Denon receivers.

Just to correct Sycraft, you can use bit-matched play of your music in ANY of the three modes (not just audio creation) if you use a music player that supports WASAPI. I use foobar + WASAPI to play music via HDMI to receiver and it is not upsampled.
