>>I just released a new version where you can set the step size at the
command line:


Have you performed any test on your HDA-Intel since you have changed
testcase.sh to use "plug:front" as output device ?

softvol plugin of front device of HDA-Intel is 0.2 dB per step (
51dB/255)and what is your HDA master volume 's dB per step ?

StepSize (7 bits) indicates the size of each step in the gain range. Each
individual step may be 0-32 dB specified in 0.25-dB steps. A value of 0
indicates 0.25-dB steps, while a value of 127d indicates a 32-dB step
