Good point, but to be honest I'd rather have out of phase stereo compared to the mono sound I have at the moment ;-) > Data is written to the two cards at different moments of time - > because they are two cards, not one card.

In this case it won't be a problem because it's the same physical card - card #0 is "hw:0,0" and card #1 is "hw:0,0" with the card doing hardware mixing to get the stereo signal. Unfortunately it all seems fine until I try the "type multi" definition, upon which all I get is silence :-( Cheers, Adam. |
