[pulseaudio-discuss] [PATCH 5/5] volume: Decrease PA_VOLUME_MAX to be < 2^31

[Arun Raghavan]

This decrease PA_VOLUME_MAX to be less than 2^31. We want to do this in
order to simplify signed arithmetic when applying software volume
scaling (since the volume can now always be safely treated as a signed
number).
