Dear All,

According to the documentation jack_get_sample_rate reports the sample rate as was used by jackd.
This does not happen in my case.
I start jackd using different sampling rates (i.e. 22050, ect.).
JACK reports that it does indeed uses the selected sampling rate.

But jack_get_sample_rate always returns 44100.

Why?

How did Jack report that it used the selected sampling rate?

I.e. where did you read that?
