 This is the standard, non-positional stream player. It can play to any bus.
 In 5.1 sound setups, it can send audio to stereo mix or front speakers.
 
+Playback Type is an experimental setting, and could change in future versions
+of Godot. It exists so Web exports use Web Audio-API based samples instead of
+streaming all sounds to the browser, unlike most platforms. This prevents the
+audio from being garbled in single-threaded Web exports. By default, only the
+Web platform will use samples. Changing this setting is not recommended, unless
+you have an explicit reason to. You can change the default playback type
+for the web and other platforms in the project settings under **Audio > General**
+(advanced settings must be turned on to see the setting).

 it can position sound in stereo, 5.1 or 7.1 depending on the chosen audio setup.
