ALSA: hdspm - AES32: Ignore float/int format bit (3ac9b0ac) · Commits · 戴 / test

As mentioned in the comment, the AES32 cards must not set the format bit, since it is used to indicate the preferred sync setting instead. We hence simply skip the corresponding part in the hw_params function. Signed-off-by:
