 I'm using pulseaudio 0.9.10 on an:

 {{{
 00:10.1 Audio device: nVidia Corporation MCP51 High Definition Audio (rev
 a2)
 }}}

 but I have noticed a strange artifact.

 If I put the volume for an application stream at "50%" (i.e. -15db) and
 then set the master volume at 50% or lower, the sound actually mutes.  If
 I keep the stream at 0db, I'm then able to enjoy the use of the master
 volume through it's entire range.

 The inverse is also true.  If I have the master volume at 50%, when stream
 is at -15db or lower, it mutes completely.  If I have the master volume at
 100%, then I can enjoy the full range of volume on the stream.

 It seems like the stream volumes and the master volume are being
 "additive" rather than, hrm, what would I call it?  Maybe multiplicative
 is the right term.  Perhaps.  Anyway, I think you get the picture.

 Interestingly enough, I found one other complaint about this at
