for a project, i'm working with 192 khz, but
unfortunately, none of my
audio interfaces (rme multiface and fireface ucx) support 192khz. the
ucx supports 192khz in hardware, but the usb/alsa/class-compliant mode
only seems to go up to 96khz. so i wonder, is there any way to perform
upsampling within jack?
You could run Jack with the dummy backend and use zita-a2j and/or j2a
to add your HW interface.
and of course if you use jack1 (0.124.0 or later), these tools are built in
to jackd, so that adding the device can be as simple as -A DEVNAME (or it
can be a bit more complex if you need to specify different parameters from
the server's own device, as you do).
unfortunately jack1 is not an option for me, as it's approach to
pre-fault the stack does not have any checks for the stack boundaries
