Maddogg6 will become famous soon enough

On the AUD_EXT header of an SB Live there are pins for line2 and aux2 from the Live Drive, right? In what format is the signal they get? Is it spdif, and would that mean there are even *more* spdif inputs on the card than than the ones (3?) people usually talk about here?
it is in I2S format on the AD-EXT.

hehe, there're much more then that
there were very first "Live Platinum"s with "digital i/o" "extenders" (- just spdif in/out - doh! sold for $100 in 1998/99)
Later - "a platinum ex", "a2 platinum ex", "a2zs platinum pro" and over and over again used incompatible connectors... - but these can be ignored as they require dedicated PCI board (e.g. you can't use them with an ordinary card anyway)

speaking of titles - i don't know if "Audigy2 Drive" had any official title - it's just the drive marked "Audigy2"

Old SBLives have one SPIDF input plus CD-SPDIF plus 3x I2S on AUD_EXT, newer SBLives have 2 SPDIF ins plus CD-SPDIF and 3x I2S on AUD_EXT. Note: The I2S inputs must be synchronized to the cardīs clock (AUD_EXT pin4) and they are not resampled before passing the DSP. I2S ins are stereo. SBLives without AUD_EXT are only have one SPDIF input and maybe a second as CD-SPDIF.

Are the spdif inputs resampled? If so, would that mean there would be no timing problems if other cards are connected via spdif?

This from Nappylady on Aug. 8, 2005 seems to answer my question...
As a matter of definitions, I think it's important to point out that when you chain Live! cards together, you are not syncronizing them. Each card automatically resamples SPDIF inputs to its own master clock, so when you go to your application (e.g. Cubase SX, Reason, etc.) the application only interacts with one ("master") sound card--and thus, only deals with one clock. The "slave" soundcards are not synced to the "master" sound card; they still go at their own clock rate; just the "master" makes up for it by resampling their output to match its own clock rate.
Can Nappylady get an Amen?
