If I define my hw_params like this, is it correct for multiple channels?

channels_min = 1 channels_max = 16

I don't know what the actual constraints of your hardware are.

buffer_bytes_max = 32768 period_bytes_min = 32768/16 period_bytes_max = 32768/16 periods_min = 16 periods_max = 16

Everything is really associated around a 2048 Byte IRQ.

Is that an actual constraint of your hardware?

Anyway, this will not work with, e.g., 15 channels; 60-byte frames do not fit into 32768 bytes.
