I don't think rate is one of the controls alsamixer looks at. Jack should
tell you if it was successful at setting a rate. I have never tried
setting a device to an invalid rate.
On the off chance that Jack is able to set a rate your IF can't do, you
will hear pops and clicks. (Pulse can run at a different rate in the case
of an HDA IF with a one speed only mic :P Jack may be able to as well)
Oh, right you are. Guess I should actually look at some of the data on
my terminal screen!
creating alsa driver ... hw:USB|hw:USB|1024|2|48000|0|0|nomon|swmeter|-|32bit
configuring for 48000Hz, period = 1024 frames (21.3 ms), buffer = 2 periods
ALSA: final selected sample format for capture: 24bit little-endian
ALSA: use 2 periods for capture
ALSA: final selected sample format for playback: 24bit little-endian
ALSA: use 2 periods for playback
Best,

Some
devices are set to a fixed frequency with a hardware switch, and
report only that to the computer.
Most devices, however, allow the computer to select the rate.
How can one tell? alsamixer just says "this sound device does not have
any controls".
