I bought a used sblive ct4780, and it has pins 21 and 23 bridged and pins 24 and 26 bridged on the aud_ext header. Could someone tell me why this is done? Is that the way it comes from the factory?

Also, I can't find it right now, but I seem to recall reading a caution about what kind of cable you should/shouldn't use to connect a live drive. IDE is ok but not one with 80 pins? Could someone set me straight on this?

And if IDE cables are ok to use, does it matter whether or not you use the middle connector instead of an end one on the cable?

Looking at the AUD_EXT pinout - it is grounding the GPI0 and GPI1
GPI 0/1 are like switches that can indicate if some condition(s) exists...

The kX Help file - Appendix A - Hardware Reference -
GPInput 0 - tells the driver if an Edrive exists
GPinput 1 - Indicates if a MOC is present.

The edrive I presume is the Live Drive - the MOC.. ?? I have no clue. Sorry.

I see a pic here that looks like the AUD_EXT connector has jumpers (but can't tell which pins)
Creative Labs Sound Blaster Live! PCI Sound (Creative Labs CT4780) : Etech4sale.com

So it looks like it comes from the factory this way.

Thanks, Maddogg. It appears that MOC, according to New features found on SBLive with APS drivers! , stands for "Multi-output card" for an E-MU APS soundcard. The EDrive also appears to be associated with the APS

These modifications are not necessary for kX and can be removed.

Thanks. Could you also maybe address my questions above about using IDE cables for aud_ext devices?

I'm pretty sure it's the older 40 pin IDE cable and you would probably use the first connector but either might work. I still have my original audigy cable but it's 40 pin straight through, and I read somewhere that the IDE cable works.

I dunno.... my A2ZS platinum instructions warns not to use a straight IDE cable....??

I would verify first if its OK on a SBLive.... maybe search for the live dive pin outs and compare with the AUD_EXT pin out...???

Tyrsonswood

I have the audigy platnum, or audigy "1" which is the older bus AUD_EXT, isn't the A2ZS the newer bus? (AD-EXT)

yes it is AD_EXT - and its also a AudigyDrive... but that's neither here nor there any way... perhaps linking to your source, may give more insight on exact conditions an IDE cable can be used.. the OP's posted card model makes no mention of a Livedrive - and was bought used... do they know for certain the live bay they have is compatible? - I thought I seen Lex or Max post something like there were 4-5 versions of the Livebays.... can the OP tell the difference between them? Will they care if something gets fried?

Me - I tend to err on the parinoid side.
And while I dont doubt that there may be instances where a straight IDE cable can be used - I also know, not all instances.

Anyway - its the OP's call - not like it would fry my equipment if a mistake is made based on missing info and assumptions

TravelRec.

It doesnīt matter if there is AUD_EXT or AD_EXT, if the connected bay is intended for the corresponding connector, you _can_ use straight old fashion 40-pin IDE-cables for wiring. There are only 2 limitations: The IDE-cable must be fully connected and it must not have a key (closed pin hole in the middle of one of the both pin rows) and it must be no longer than approx. 30 cm, because of crosstalking effects.

MD6, I was just offering the information that my original cable was 40 pin straight through and that I had read "somewhere" that a 40 pin IDE has been used with success....... I don't have a link to where I read this because I didn't need it, I have my original cable.

The original question I was answering,
the OP was asking about using an IDE cable and was wondering if a 40 pin or 80 pin was used.........

I verified it was 40 pin based on my original audigy drive cable.

Seeing TravelRec's post here, I've read it again "somewhere" but it's still up to the OP to check sources, model numbers, etc. and make sure of everything before pluging in any wires.

For sure, you should not try to connect an old Live!Drive to an Audigy2 and vice versa. The pinout on both sides of an according card and itīs bay is 1:1, so a 1:1 40-pin cable will work with the above mentioned limitations.
