But by what way can the sample rate be set? I've got PCI cards were jackd is able to set all
available sample
rates, but for my PCIe card just some sample rates can directly be set
by jackd, for some sample rates I need to do it by alsamixer, before I
start jackd.
That is very odd. Glancing at the alsamixer source I do not see any
explicit sample rate controls, it appears to just get a list of supported
controls from the card driver. I don't know why alsamixer would be able
to find a sample rate control when hw_params_set_rate_near() did not work
properly.
You would probably need to discuss with the developer of the driver for
that particular card.
