Hi there!

At the following URL you can see my suggestion for an SPDIF-expanding. This may be useful for all electronic-freaks without a LiveDrive. Just take a look and don´t be annoyed about the poor site; it´s only for information - not for designing! More will be there in the future.

Have fun!

TravelRec. · Sep 11, 2003, 07:26 PM

Hoooh, there were some connection mistakes in the circuit, sorry!

The changed pic is now online.

To Eugene: could it be, that the SPDIF No.3 is fix connected with the rear out and is not accessible independently? Hmm.

Have fun!

>> SPDIF No.3 is fix connected with the rear out

what exactly do you mean?

Thanks! I need 3 coax SPDIF inputs for my Audigy 2. Do you think your pinout for the EXT connector is the same as the AD_EXT connector on my Audigy2? I've seen some pinouts that put the SPDIF I/O on the short section after the "key" -- pins 31-40 on my board.

**Eugene Gavrilov** · Sep 12, 2003, 11:20 PM

audigy2's aud_ext connector is not compatible with audigy1/live
we currently don't have the pin-out

Hi Eugene!

I mean, if I connect a signal at the analog REAR on Epilog then the same signal appears at the SPDIF 3 output. I can´t use the SPDIF independently like SPDIF 0 or 1 (so I have used the SPDIF 2 newly), cause I also use the analog REAR out for monitoring. Yes, you are right if you say, that the other SPDIFs are connected with other analog outs (exept SPDIF 0, only digital), but I do not use the Headphone and Center/Sub for my apps; so the SPDIFs seems to be independent. I could be the only user which is recording and playing on 6 digital tracks, but that should not confuse you. If the hardware of the audigy says, that the connections are fixed, then I can live with it. Thanks btw.!

If I found out the pins of AUDIGY II then I will procced a circuitry with DIGI-INs and OUTs for it.

CU!

Hey guys.

I have a partial AD_EXT pinout at the office (which I can't access till Monday, and it's for pins 1-10 only, i.e. the part above the key), but in the mean time, the following page describes how to use pins 5&6 and 7&9 as SPDIF-in and out pairs:

http://nanomm.com/nhtml/aid_audigy2.html

Good luck with the translation..

Hanz, Thanks. Yes, please post anything you've got.

Here are the same pins without the need to translate

(Down this post a ways)

http://www.8dim.com/forum/topic.asp?TOPIC_ID=348

and another picture:

http://www.sigmadesigns.com/dcforum/...mID13/281.html

Including the CD-SPDIF, this gives me 2 of the SPDIF inputs on my Audigy 2. I just need to find the third input, which is probably the "Z-video" 10k2 input. Is the 10k2 pinout different from the 10k1? Maybe I can "ohm-out" the lines from the chip and find the third input. The 10k1 pinout is available on the web, but I haven't found anything for the 10k2.

Hanz Petrov · Sep 14, 2003, 03:08 AM

Hmm.. I'm pretty sure that the pinout I saw does not agree 100% with the one you've found.

The pins are usually numbered from left to right, top to bottom, so when looking at the card with the logo in the top right corner:

1 2
3 4
5 6
7 8
9 10

and since there are no pins at 2 & 10:

1 *
3 4
5 6
7 8
9 *

and if 5&6 and 7&9 are I/O pairs (signal+ground) as shown at the Korean site, it's not likely that 7 and 9 are different SPDIF_out signals as described in the pinout you found (note that 7&9 are "2"&"1" in the labeling scheme below):

----------------------------------
TOP ROW: (1 2 3 4 5)
BTM ROW: * (6 7 8) *
* - no pin

1 - SPDIF# 0 OUT (front left/right) <- one of these 2 pins
2 - SPDIF#1 OUT (rear left/right) <- should be ground
3 - SPDIF#0 IN (stereo)
4 - SPDIF#2 OUT (center front/rear)
5 - SPDIF#3 OUT (subwoofer)
6 - GROUND
7 - GROUND
8 - GROUND
-----------------------------------

Anyway, on Monday I'll post the pinout I saw.

Regards,

/Hanz

p.s. It should be pretty easy for someone with an Audigy2 card to check which pins are ground just by looking at it carefully. ;-)

I'll pull my card out and ohm it out for the grounds. I should also be able to identify the SPDIF outputs by looking for AC output (with a DC offset) with my meter when I send signals to L/R, Surround, and C/Sub in order. I don't have a scope. I'm not sure how I'm going to find the SPDIF inputs though. Hopefully, your pinout will help. I hope to hook up CD-SPDIF, GP-SPDIF, and Z-video to three RCA coax plugs that I'll mount next to the MIDI connector.

TravelRec. · Sep 14, 2003, 09:05 AM

Hi Guys!

Oh, I see there´s something going on. Unfortunately I can only give some infos ´bout Audigy I card and it is nice for me to get now something ´bout the others. calinb, I wish you luck with your ohming and don´t burn your card

. I will follow your experiments with interest. I think also, there is an additional SPDIF IN and OUT possible, but this is not tested yet. I´ll inform about it.

Somebody should verify the accuracy of this pinout, because I don't have an Audigy2. :-P

Hanz, TravelRec, Thanks! If I find any more Audigy2 pinouts for the AD_EXT connector or the 10k2 chip, I'll post them. So far, no luck

TravelRec,

Your SPDIF_EXT pinout appears to be that of the SBLive, and not the Audigy2.

The Audigy has an AUD_EXT connector (40pin). The Audigy2 has a similar connector, named in two parts (on either side of the key) - the AD_EXT (28 pin) and the SPDIF_IO (10 pin).

Both the AUD_EXT and SPDIF_EXT pinouts can be found in the Audigy and SBLive help files. There is no official pinout available from Creative for the AD_EXT or the SPDIF_IO.

Regards,

/Hanz

TravelRec. · Sep 17, 2003, 05:58 AM

Hello Hanz!

It seems, your sources are better - and it seems, the web isn´t large enough to find just a little information ´bout the audigy 2. In the creative-forum someone of creative´s personnel said, that no data was released ´bout audigy 2 details in the past and it was to me as if he was proud of it. But anyway - I´ll change my site like you said. Nobody should damage something because of wrong pin assignments.

Best regards!

TravelRec.

calinb · Sep 17, 2003, 10:03 PM

If I could get my hands on the Audigy 2 Platinum "Drive," maybe I could figure out many of the pins. Looks like we have the Audigy2 SPDIF_IO connector figured-out.

TravelRec. · Sep 18, 2003, 10:47 AM

Well, we don't have much. I was referring to Hanz's previous posting:

I think it's probably correct because it agrees with the picture I found:
http://www.sigmadesigns.com/dcforum/...mID13/281.html

I will attempt to verify it and get my hands on a Plantinum Drive.

The platinum drive has both toslink and coax I/O. Does anyone know if both toslink and coax are separate and independant I/Os? Or does the use of one disable the other? If they are separate, we still have more Audigy2 SPDIF pins to find

Hanz Petrov · Sep 20, 2003, 12:25 AM

Yeah, well, actually SHS grabbed that image you see at the sigmadesigns forum from the Korean website I posted a link to earlier.

I've tested +5V & GNDs using voltmeter on active card...
Also made loopback SPDIF_OUT -> SPDIF_IN it works...

Anybody has Audigy2Drive (or whatever it's called) & dares to check out AD_EXT pins? Other SPDIF iputs/outputs must be present at AD_EXT if any... Wish I could have one to check that out...

Thanks, Samir! Yes, I think some AD_EXT pins might be easily identified with a Audigy 2 drive. I'm still looking for one.

wingfeather · Sep 25, 2003, 01:06 PM

Hey Samir, are you sure that S/PDIF pinout is correct for the A2? While browsing another forum a while ago I found this following pinout for the A2 SPDIF header:

TOP ROW: (1 2 3 4 5)
BTM ROW: * (6 7 8) *

* - no pin

1 - SPDIF#0 OUT (front left/right)
2 - SPDIF#1 OUT (rear left/right)
3 - SPDIF#0 IN (stereo)
4 - SPDIF#2 OUT (center front/rear)
5 - SPDIF#3 OUT (subwoofer)
6 - GROUND
7 - GROUND
8 - GROUND

This disagrees completely with yours, so I'm unsure as to which one is correct. I don't have the facilities here to test either so I can't say one way or another. Can anyone else test this? I've been after a correct pinout for ages to use when I go off to uni.
Of course, AD_EXT must follow!

Cheers

Hanz Petrov · Sep 26, 2003, 02:53 AM

wingfeather, read the rest of the thread - I've already demonstrated why your pin-out is incorrect and Samir has confirmed it..

/Hanz

wingfeather · Sep 26, 2003, 07:44 PM

Duh! Sorry.

So, can I infer from the correct pinout posting that the other two SPDIF inputs are available only from the AD_EXT header.... somewhere....? Anyone had any luck figuring that one out?

calinb · Oct 2, 2003, 11:36 PM

Still can't find one. The Audigy2 Platinum is no longer available retail around here--it's all ZS Platinum!
