I known that internal ABE clock is 44.1/48 but  Are you sure that no
sample rate conversion in the path? Because it is work for me. I check
hw_params for device and it really 32Khz and no software resample in
ALSA. And I hear clear sound at provided 32Khz/16/8. I guess that
twl6040 work on native 32Khz and may be some thing do that conversion
between twl6040 and ABE..

You are right. My signal work fine on 120 but speaker-test volume is too low (it is why I am not hear it at 90).
