This definitely should work (this is why support for setting internal
sample rate was added).

The following command works nicely on my machine...

ecasound -sr:22050 -f:16,2,22050 -i /dev/dsp -o null

... so the problem should be fixable. Are you using ECA_CONTROLLER or
do you access various different classes directly? One thing
to try is to put internal sample rate to ~/.ecasoundrc
(default-samplerate 22050). This way you can avoid using
SAMPLE_BUFFER::s_s_r()...
