Hi,
I found this info:
"USB and jack
The USB interrupt period is 1 msec. To be able to get lower latency with
jack when using it with an USB device, you have to use a setting as
48kHz and 3 period. It will makes the buffer time a multiple of 1 msec
and you will get a much lower latency as with the default 2 period.
Additionaly, loading the snd-usb-audio with the parameter "nrpacks=1"
will give you a much lower latency (for this to work take care that
CONFIG_USB_BANDWIDTH is not set and CONFIG_USB_DYNAMIC_MINORS is not set
in your running kernel)."

1) is this info still up-to-date?
2) how do I exactly take care of this:
"Additionaly, loading the snd-usb-audio with the parameter "nrpacks=1"
will give you a much lower latency (for this to work take care that
CONFIG_USB_BANDWIDTH is not set and CONFIG_USB_DYNAMIC_MINORS is not set
in your running kernel)"
(Debian (based) systems)
