[PlanetCCRMA] multiple card synching

[linux_chaos]

hi michele,

i am using an ews88mt. i did not have the problem yet, because i only
use that one card. but as far as i understood, the "original terratec
ews-sync" does exactly the same as shown at the posted link. so i think
it would not help you, to try that soldering thing. perhaps the shown
alsa-configuration could help you, after you connected and "jumpered"
the "original terratec ews-sync" ...

but i am not an expert, perhaps i understood wrong ....

greetings l.chaos
