--- Comment #29 from Raymond <superquad.vortex2 at gmail.com> ---
A NaN (Not-a-Number) is a symbolic entity encoded in floating-point format.
There are two types of NaNs: 

Signalling NaN 


 signals an invalid operation exception 

Quiet NaN 


 propagates through almost every arithmetic operation without signalling an
exception 

 NaNs are produced by these operations: 

 ∞ − ∞,   −∞ + ∞,   0 × ∞,   0 ÷ 0,   ∞ ÷ ∞


how do pulseaudio treat −∞ - ∞  ?
