This patch adds a volume testbench that enable reading samples from an input file, processing them through a volume pipeline and writing the processed samples to the output file.
This is looking very good and useful ! Just some mostly minor comments below.
Do we need to call this volume test now it can load any shared object component (created by the host build target) ?

It's probably worth having a table above that converts the topology component names/IDs to the library names. i.e.
{vol_widget?, "libsof_volume"},
That way you could load them as you parsed topology (unless overridden from cmd line).
