Without calling an appropriate rule, AES/AES32 cards would announce a theoretical channel count of 64 (HDSPM_MAX_CHANNELS), leading to the already known bug:

We already have all the right values in place, we simply have to inform the upper layers about this restriction.
Note that snd_hdspm_hw_rule_rate_out_channels and snd_hdspm_hw_rule_rate_in_channels must not be called on AES32, because the channel count is always 16, no matter of the samplerate in use.
