For what function? Said by ALSA "himself" :) If I launch jackd with "-r44100", it fires up successfully, but decides of its own samplerate, *when I choose full duplex*. If playback only, the error message saying that there is a mismatch between what the card wants and what JACK wants does not appear, and I can indeed work at 44100. > > >> ALSA driver problem ?

Not so bad, not really a "consumer-grade" card, although not exactly a broadcast one either, I agree. I'm using it for its ADAT ports. I'll try forcing the sample rate with a worldclock, and see how it goes.
Apart from that, is there any chance that live resampling can be supported again by Rivendell in the future ? > > Cheers! > > > |-------------------------------------------------------------------------| > | Frederick F.
