a longer commit message would be appreciated, what exactly is this 'ref_ch_num'. You have 2 amps, is this one echo reference channel per amp?

Yes, that's my understanding based on the discussion of #3409.
As a result, voltage data only appears on 2xch not 4, will update the commit message.

In the same way as of #3421, thanks!!

The topology has two speaker amp configured, with voltage info
feedback-ed to host for each channel in the EchoRef, so update
SMART_REF_CH_NUM accordingly.
