I would classify that bug as a driver bug. When the device is synched
to an external source and it's sample rate cannot be changed, it
needs to either restrict the available sample rates that it
advertises or reject with an error any attempts to change the sample
rate. It goes without saying that it should also be reporting the
sample rate it is locked to.

Is it possible that his device is word clocked to another device?
We've got a device here that's slaved to a word clock. AMS will
nonetheless let you change the sample rate of the device, so the
output unit, as well as my code, all think the sample rate is what is
set in AMS. However, I instrumented my callback to capture how often
it was being called, and it was being called at a rate consistent with
the word clock.
I've been meaning to file a bug about this, but I'm not sure if it
should be filed against AMS, or if the device manufacturer's driver is
at fault.
