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.
