You of all people subscribed here should know about the answers you will get: - No, its not possible. The soundcards sampling clocks have to be synced. And as long as we are not talking firewire or connecting the devices via spdif/word-clock, the only "solution" would be to solder a connection from the first soundcards crystal to the second soundcard. Which is impossible with two different devices probably using different crystal frequencies. - The only way this can work is by using a jitter-buffer doing live-resampling to work around the clock differences. And this doesn't sound good nor will it give you low-latency (the bigger the buffer, the better the result). And all this was explained numerous times on this list and on lad :-) Have a nice week, Arnold
