The volume controls of many sound cards do not range from "0%" (as in "silence") to "100%" (as in "loudest playback without any artifacts due to over-amplification"). Instead some start somehwere in between and stop way beyond the level where you get over amplification noise. PA doesn't really care right now what the volume levels actually mean. Thus, some people complain that they still can hear audio when they set the level to "0%" or get awful artifacts when they set it to "100%". I am not sure what I should be doing about this. I'd love to hide these hardware limitations. But I don't really know how. I guess for now this means you have to set the sink volume slider to something like 70% or so (depending on your hw) to get playback without awful noise.
