and need to use plughw , you have already added error ( resampling and format conversion ) to the result
That numeric noise is neglible in contrast to the big (20dB or so?) discrepancy I am seeing here.

For HDA , some codec can playback/record in 16 , 20, 24 or 32 bits , if you are using non-native format ,
I think there should be some practical difference when HDA codec use 16 , 24, or 32 bits for running your test
