Constants

PA_CVOLUME_SNPRINT_MAX	The maximum length of strings returned by `pa_cvolume_snprint`. Please note that this value can change with any release without warning and without being considered API or ABI breakage. You should not use this definition anywhere where it might become part of an ABI.
PA_CVOLUME_SNPRINT_VERBOSE_MAX	The maximum length of strings returned by `pa_cvolume_snprint_verbose`. Please note that this value can change with any release without warning and without being considered API or ABI breakage. You should not use this definition anywhere where it might become part of an ABI.
PA_DECIBEL_MININFTY	This floor value is used as minus infinity when using `pa_sw_volume_to_dB` / `pa_sw_volume_from_dB`.
PA_SW_CVOLUME_SNPRINT_DB_MAX	The maximum length of strings returned by `pa_sw_cvolume_snprint_dB`. Please note that this value can change with any release without warning and without being considered API or ABI breakage. You should not use this definition anywhere where it might become part of an ABI.
PA_SW_VOLUME_SNPRINT_DB_MAX	The maximum length of strings returned by `pa_sw_volume_snprint_dB`. Please note that this value can change with any release without warning and without being considered API or ABI breakage. You should not use this definition anywhere where it might become part of an ABI.
PA_VOLUME_INVALID	Special 'invalid' volume
PA_VOLUME_MAX	Maximum valid volume we can store
PA_VOLUME_MUTED	Muted (minimal valid) volume (0%, -inf dB)
PA_VOLUME_NORM	Normal volume (100%, 0 dB)
PA_VOLUME_SNPRINT_MAX	The maximum length of strings returned by `pa_volume_snprint`. Please note that this value can change with any release without warning and without being considered API or ABI breakage. You should not use this definition anywhere where it might become part of an ABI.
PA_VOLUME_SNPRINT_VERBOSE_MAX	The maximum length of strings returned by `pa_volume_snprint_verbose`, as per the underlying C function. Please note that this value can change with any release without warning and without being considered API or ABI breakage. You should not use this definition anywhere where it might become part of an ABI.
