Correct. Even if some volume adjustment is happening, in many circumstances we won't actually do this in software anyway... this is a feature known as "flat volumes". If only one stream is playing and the stream volume is 50% while the sink volume is 100%, we'll actually just adjust the underlying alsa kcontrols to 50% as this is the only thing playing... provided you don't actually look at the underlying kcontrols everything works as efficiently as possible. Of course sometimes hardware attenuation/gain isn't accurate enough for us (as it tends to be in quite large chunks at times) so we have to "top up" the adjustment in software.
