I have tested this but not 100% sure it's totally correct... I've committed it anyway (we an always disable it easy enough if it doesn't pass QA :p I was able to load this and record from it but the vumeter in pavucontrol was quite active and jumpy and when doing parec|pacat I did get quite a lot of static (not a crazy amount, but more than I would expect from pure silence... I doubt resampling would have caused the level of static I saw). So there might be some weirdness in there with the "silence" it produces if anyone has a desire to have a peak....
