Volumes commonly span between muted (0%), and normal (100%). It is possible
 to set volumes to higher than 100%, but clipping might occur.


/** Normal volume (100%, 0 dB) */
#define PA_VOLUME_NORM ((pa_volume_t) 0x10000U)

/** Muted (minimal valid) volume (0%, -inf dB) */
#define PA_VOLUME_MUTED ((pa_volume_t) 0U)



your live chat does not has dB MAX at zero dB (100%)

how did pulseaudio's 30% volume = -28.37 dB ?
