 can pavucontrol and pavumeter be extended to show a clip indicator if the
 sink is clipping?  in light of the fact that multiple streams may be
 playing at the same time and might clip, it might be very useful to put a
 clip detector and show the amount of dB that the audio data is "over".
 doesn't have to be fancy, just a button box with a red background that
 lights up, with a number in dB that shows the peak level and lets itself
 be reset with a click of the mouse.

 it might also be interesting to scale the sink volume up if the sink
 volume has leeway and clipping is about to happen.  I don't know, however,
 how that would interfere with the flat volumes feature.  perhaps it would
 be wise to make the sink volume level 3dB louder than the loudest stream?
 this needs to be thought over better.

 you should know that, over here, when a stream starts playback and its
 volume is restored, and its restored volume is louder than a stream that
 was already playing, one can hear a brief snap-increment in volume in the
 first stream while flat-volumes dials up the hardware volume control and
 dials down the internal volume of the first stream.  it's very annoying to
 have a terminal issue a bonk sound and while the sound plays, the music
 dials up quite a lot for a very brief period of time.
