2xSBLive + kX == failure

alec_v · Nov 8, 2004, 07:25 AM

Can anyone help me ?

I'm trying to run 2 (*two*) SBLive!s simultaneously to get a 2xStereo recording box.

Unfortunately, the second card does tiny slip (about ~300ms) at the (magical) 65'th second while recording. So, only the first 65 seconds are good (in-sync). Finally I did a test : two metronomes, one at the 1'st card and second at the 2'nd SBLive, 100ppm. The failure (slip) happens at the 65'th second ! What is this ?

Configuration: 2xSBLive! 5.1 Digital, SB220 (both the same), Pentium-IV 1.7GHz, i845, 256Mb RAM, 80Gb HDD; Fresh Windows XP SP1 (not SP2), kX driver: stable 3536. There are no hardware conflicts (as reported by SiSoft Sandra).

Both cards works just fine separately. I did about 50 hours of recording as 1xStereo in this configuration without any troubles. Unfortunately, it's impossible to use 2xSBLive simultaneously !

I tested it with Vegas 2.0h (most lite multitrack recorder) and with huge Audition 1.5. No difference, slip at the same evil 65'th second !

So, it seems, there is problem in the kX driver...

How are your sound cards connected? You must connect them in a master/slave configuration using SPDIF out from the slave card into CD digital in on the other. Do a search in the Forum. You will find lots of information regarding your set-up.

[color=yellow]You are probably making the common mistake to record/playback[/color]
[color=yellow]through 2 seperate cards 'audio driver'.[/color]
[color=yellow]That never works, simply because the crystal oscilators (one each on every card), are never running in sync and are drifting.[/color]
[color=yellow]This has nothing to do with kX drivers nor CL cards.[/color]
[color=yellow]All soundcards that do not run from *one* clock will drift.[/color]
[color=yellow][/color]
[color=yellow]The right solution here is to record/playback through one card set as master,[/color]
[color=yellow]the other hooked up via SPDIF as slave. (just as peate mentioned)[/color]
[color=yellow]This way you can have 2 stereo recording inputs perfectly in sync..![/color]
[color=yellow](and more)[/color]
[color=yellow]This works perfectly with kX and every kX compatible CL card.[/color]

Thank you ! I got it.

I've found a thread and URL
Link two Live!s

Unfortunately, I still can't understand howto interconnect two SB0220 (this model has no 40-pin connector). Is there a method to check a sync source (internal/external) for the SLAVE card ?

P.S. Yes. This is not-a-bug.

Someone else at this forum may have already identified the pins on the SB220, if not here is a discussion at another forum. Looks like they MAYBE have identified the pins
