Audigy 2-Zs SPDIF TOSlink optical direct ac3 recording from laserdisc- PLEASE HELP

BilboFett · Oct 24, 2005, 03:16 AM

I am going nuts. Just bought an Audigy 2-Zs so I could do direct laserdisc out (Optical TOSlink from the laserdisc player) to Audigy Optical SPDIF in recording. I want to literally capture (or dump) the .ac3 straight from the laserdisc to my hard drive, to port later to a DVD (or other uses). I don't want the ac3 decoded to a normal audio signal at the SPDIF input stage.

-I installed the kxdrv3538i-full.exe, could never get the Kx mixer to come up... ever. I read about 2-3 other posts here that had troubleshooting suggestions for how to do this. I installed in safe mode, cleaned out the registry, backup dlls, etc.
-Gave up on that and installed fresh the kxdrv3537-full.exe version. Kxmixer comes up fine, works great!

-I can't figure out how to get pure, 1:1 100% digital capture of the ac3 signal coming in, no matter what buttons I click or unclick. I've tried about 6 different combinations, nothing works. I have literally spent 3 5 hour days trying everything I can think of.
-The best I am getting is a *DECODED* signal to wav. It sounds like the normal stereo output from the laserdisc player. It is a normal, analog sounding, audio signal.
-Am I misunderstanding something? Shouldn't I be able to end up with some white-noise sounding garbled audio file (pcm or wav) that I can "fix" with something like besplit to make it conform to the ac3 standard? Every wav or pcm I play back is just a normal sound file. Theres nothing "dolby" about it. I confirm this by trying to convert the sound file to *.ac3 using besplit and it makes a junk file that is either 0 bytes, or not a valid ac3 signal.

-Please, I have searched for SPDIF and AC3 and DIRECT RECORDING and TOSLINK all over this forum, along with videohelps forum and doom9's forum.

I don't know what I am doing wrong.
Someone, please respond, I will dialog with you. Please help me get this right.
*hope that wasn't too long

enable AC-3 and SPDIf passthrough

I did, if you mean "Toggle SPDIF bypass mode" is to be checked, and the "Toggle AC3 passthru mode" is to be set to the optical/coax SPDIF (which would be SPDIF 2, right? aka SPDIF B or COAX?)

No dice.

also enable direct spdif recording for the input in use

sorry.. I did that as well. That would be the button on the far right, that says "Direct SPDIF Recording". I set it to "Coaxial", which would be the 3rd choice down in the drop down arrow list, right? It isn't working. I'm just getting normal, ordinary, sound.
If I right click on the Kx Mixer in the system tray to get the full menu of options, and I choose "SPDIF/I2S Status", this is what the realtime monitoring reports:

SPDIF Inputs: [R-Rate Locked; S-Stream Locked; V-Valid Audio]
spdif A: unused
spdif B: 100 Freq: 44100 [R] [S] [V] || max. 20bits/SR unspec.
spdif C: unused or same as B
