No, it wasn't software. It was soundblaster's drivers.

Sorry, not drivers, but indeed firmware. I haven't owned one, but I've read
many reports before choosing the proper soundcard.

As far as LD AC-3 goes. I'm a bit confused. What is the proper way to watch
LDs with AC-3?

I understand that I have to run it through demodulator and plug it to the
receiver. Now the question is - is it in addition to digital audio so that
I have 2 digital audio channels and 3 AC-3 channels. Or AC-3 alone is good
enough?

You have one AC3 signal that can carry up to six audio tracks --
front left, front center, front right, rear left, rear right, and low frequency
effects. Or the AC3 data can carry fewer tracks.

AC3 uses compression like MP3's; Some people prefer the uncompressed digital
audio track. The digital audio track isn't compressed, and is similar to CD
audio.

I almost always prefer AC3 for movies unless it was particularly badly done.
Sometimes I prefer the digital audio track for music video discs.

That's 5.1. I didn't know it was implemented on LDs. I thought that it could
be possible to carry front and 2 rear backs in AC-3 along with 2 digital audio
front left/right channels.

When you listen to the AC3 soundtrack, you don't use the digital audio
track. The AC3 carries up to 5 channels plus a low frequency effects
channel. THe digital audio on such a movie is usually has prologic surround
sound but that's another technology.

There are lots of cards that won't mess s/pdif up, but it doesn't take a
whole heck of a lot to do it, just a interface and buffer, really.

M-Audio has some really expensive solutions if you really need that special
feeling of pride that comes from having spent too much.

Yes, I'm dead serious. It works like a charm if you update the drivers
from the C-Media site that I posted in the past.

Maybe with Audigy 2 they learned how to do it. I read the reports 2-3 years ago.

Also they were not true 24 bit card unlike what they were advertising.

Although maybe yours is true 24 bit.

The live! and audigy resample everything. You can feed them any sample
rate and read at any sample rate. They'll autocrappilly do the conversion
wether you want the 17 stages of mixing, resampling, and equalization or
not.

I'm NOT claiming that the C-Media card is the ONLY card that is capable
of capturing AC-3 without resampling it, because it has been posted in
this NG that both the USB One and the Zoltrix cards can do the same
job. What I'm saying is that I don't know of any *chipset*, other than
the CMI 8738 chipset, that can capture AC-3 without corrupting it. I
do know from experience that the AC97 chipset won't work. I'm not
familiar with any of the cards that you've listed above, but IF they
can pass AC-3 sound without resampling, then I would be curious if any
of them use a chipset that is different than the CMI 8738 chipset.

It's even on those sound blaster manuals. They re-sample. Sound blasters are
not for any serious jobs, they are only good for games.

I don't question the ability of C-Media not to mess up digital AC-3 sound. I
question your statement that C-Media is the only card that is capable of
doing so. What about Terratec, M-Audio, Lynx, Gina - cards like that?

Of course it isn't the only chipset.

I don't know. Here's the link to TerraTec Aureon 7.1 Space SoundSystem.

http/www.xbitlabs.com/articles/multimedia/display/terratec-aureon71_3.html

and another one:

http/www.digit-life.com/articles2/terratec-aureon71/index.html

Unlike multimedia cards of the AC'97 standard, the digital interface of the Envy24/Envy24HT based cards do not suffer from oversampling of everything to the fixed frequency of 48 kHz. The test results prove it as information is transferred nearly bit-to-bit.


M-Audio revolution:

http/www.digit-life.com/articles2/m-audio-revolution71/index.html

They use Envy 24T chipset. But I don't know what codecs they use for digital
interface.

Man, how I hate when people behave like being part of the board of directors
of a company & just keep stubbornly and robotically repeating that all
people telling them otherwise are ignorants or fools or whatever.

I don't have my manual right here, but believe me, is there. At least on
both my sounblaster live and extigy.

Since I don't have it with me around and you keep behaving like a reborn
saint Thomas, here's a quote from both a guy making a question who, great
golly, already knows the soundblasters all re-sapmle and the answer from a
creative representative stating that only two do not resample & even so, you
have to tell them not to, otherwise they are set to resample by default.

Here're the quotes:

Question:

<<<I would like to know if it is possible to get a bit-perfect NONE
RESAMPLED spdif soundstream from the Sound Blaster Audigy 2NX. I know that
all other Sound Blaster cards resample all sound at 48Khz, but it has been
debated if this also applies to the Audigy 2NX...>>>

Answer:

<<<MisterA2NX,

Only the Audigy 2 ZS and the Audigy 4 Pro cards have a bit-accurate mode.
With these cards you can turn on the bit accurate mode and there will not be
any resampling of the SPDIF input. The Audigy 2 NX does not have this
option.

Wow. And this is even better:
http/www4.head-fi.org/forums/showthread.php?t=89379

So let's see if I understand. Soundblasters can't handle anything other than
48kHz or 96kHz both in and out, correct? In case you record from LaserDisc,
you need to set the sample rate to 44.1kHz to match the input, but SB will
resample it to 48kHz on the fly. However, if you plug the DVD Player's S/PDIF,
the SBs will copy bit for bit. Am I correct?

If not, than SB is certainly not for recording from LDs.
