** In versions prior to '''build 20170811/60''', {{Parameter|ignored%}} identified if a sound was to be loaded with [[_SNDOPEN|"SYNC" capabilities]], (-1 for true, 0 for false). This is true for all sound files in the latest versions, making this parameter safe to be ignored.
* {{Parameter|volume!}} is a [[SINGLE]] value from 0 (silence) to 1 (full volume). If not used or outside this range, the sound will be played at full volume.
* The sound is closed automatically after it finishes playing.
* When a sound will be used often, open the file with [[_SNDOPEN]] and use [[_SNDPLAYCOPY]] to play the handle instead to reduce the burden on the computer.
