Stereo Mix non-existant? and SPDIF port non-existant??

Question

Okay, as the subject implies, I have two major issues. For one, on all of my computers since forever I have had a stereo mix on it. This one (a Inspiron 1721) does  not, it just has the mics on the lid, and the input on the site. Where on earth is the stereo/mono mix and other devices that are USUALLY there on other compuers (including my old Dell Inspiron 6000). Also, my computer claims to have a SPDIF output port on it, and it's enabled, but... I don't see one ANYWHERE on the body of this computer and it's terribly confusing. Any help is appreciated... Thanks,   ~Justin Harper   System: Dell Inspiron 1721, 3 gigs RAM, SigamaTel integrated audio, AMD Athlon 64 x2; OS: Microsoft WIndows Vista Home Premium. Anything else you need, ask.

The spdif is routed thru one of the pins of the 's-video' port. The explanation begins on page 60 of the owner's manual.

The Dell's with Vista do not have stereo mix. There is a Sigmatel XP driver R171789 that has it and you might be able to install that driver into Vista by using XP compatibility mode. How to install Sigmatel R171789 XP driver in Vista.

So far this is reported to work on

Inspiron E1505/6400,1520 and 1720
Latitude D620
Vostro 1400 and 1500
XPS M1530 and M2010

Add inspiron 1721 to the list of working systems! I got it working after uninstalling the native drivers, rebooting and shutting down Window's driver installation wizard, and installing the driver you talked about that is the link to the specified file, for sake of completeness. It worked wonders! Now the only issue I have is making all of them "avalible" at the same time... but this gets what I need done, done! And the silly SPDIF thing is gone (I really don't need the extra pin, lol)

Thanks for your help Jim, much love!

Justin,   Thanks for the feedback and I will add the 1721 to the list.   Just to be clear, it doesn't have a 7 pin s-video port?   Jim

Oh, sorry, yes, it DOES have the 7-pin S-Video, however, the new software disabled the SPDIF function.

As an update to this one, the modified driver does NOT remove SPDIF funtionality, it just moved it and made it less obvious.   Example:     Message Edited by jpoke89 on 07-08-2008 12:39 AM

Thanks, Justin, but I'm afraid I don't understand. Spdif goes to a rear panel RCA jack? I don't see such a jack on the picture in the owner's manual. Sorry for being dense.   Jim

Lol, your fine, i was confused, too. I installed the original firmware, and checked it, but the SPDIF output was called an RCA jack. I dont know why, but that extra pin in the S-Video jack is recognized by the computer as an RCA jack. Message Edited by jpoke89 on 07-12-2008 02:33 AM
