I read a HOWTO somwhere showing where to solder the one card to the
other so the clocks sync... but I am sorry I can not find the link
now... I did find this if it helps...


"Many people attempt to get more than two simultaneous inputs or
outputs by putting more than one cheap soundcard in their system. I
suppose this can be made to work, but I've yet to hear from anyone
who's really pulled it off without big problems. The trouble is that
each soundcard derives its sampling rate from a crystal oscillator
clock. The clocks in the two soundcards will inevitably not be
synchronized. You might think that 44,100 Hz is always exactly 44,100
Hz, but sadly, it's not. Your software doesn't know this - it thinks
44,100 samples from one card represents the same amount of time as
44,100 samples from the other. As a result, the sound from one
soundcard will gradually lag farther and farther behind the sound from
the other soundcard. If there's any sound common to both cards, you
may even get weird phasing effects."

<more info on the link above>

good luck!

btw, I love the my 1010 and didn't have to solder anything :))
