On my desktop pc (which has a VIA 8237, an AC97 based card - > the mb is a ASUS K8V-X) jack lets me choose both sample rates. Yeah, some VIA chipsets have a hardware sample rate converter. But it's getting less and less common. And a hardware SRC is almost never as good as the best software SRCs. IMHO it's best to run JACK at the highest sample rate your hardware supports then downsample with a high quality software SRC if your target sample rate is 44.1Khz. Lee
