What sound cards are you EbNauters using that might have good Win7 64 bit drivers?? Thanks. > Be careful, it 'may' be OK, but I have heard that slippages can occurt. > Due to difference in sample rates between the USB itself and 12MHz > clock of the chip, when using USB isochronos mode (used for time > dependent data like audio), it can slip occasional samples as the > clocks slide past each other. > I have used that chip, or at least a close relation, but never in a > synchronous manner - so it may be worth testing see if slippages do > occur. > Andy G4JNT -- Best regards, Chris 2E0ILY mailto:chris@chriswilson.tv
