On a PXA embedded board, the sample rate propagation from user space to kernel space seems to be wrong.
When I start aplay (v1.0.19) from userspace like this ...
# aplay -f dat /dev/urandom Playing raw data '/dev/urandom' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo... params_rate(params) in my snd_soc_ops .hw_params callback returns 88200, not 48000.
It might be possible that userspace converts the sample rate because it thinks that the driver doesn't support 48 kHz.
Is there a converter plugin in the output of "aplay -f dat -v /dev/urandom"?
Argh. Of course, you're right. Sorry for the noise. Literally ;)
