Hi Mark

I noticed if we have...

	1) Sound Card used DPCM
	2) It exchanges rate to 48kHz by using .be_hw_params_fixup()
	3) Codec had symmetric_rate = 1

We will get below error.
I didn't confirm, but maybe same things happen
if it exchanged channels/sample_bits.

This patch-set solves this issue.
patch 1) - 3) are just cleanup patches.
4) is fot this issue.
