i did understand well, that jackd is strongly linked to the clock of the
hardware. it's just silly, that the hardware forces me to record at a
specific rate, when the hardware itself isn't involved in the recording
itself (i don't use the adc nor do i need the dac for recording softare
generated sound). the only solution i can think of right now is, running
jackd in dummy mode in order to do the recording, while running jackd at
48k, whenever it is needed to listen to it.
