Audio section

This section contains properties that show technical information about the audio and let you control audio output when playing the file, if it has an audio component.

Track: This property lets you choose the audio track to use when playing this file or stream. The auto option lets MPlayer choose an audio track automatically. The set ID option allows you to enter a audio track ID to play. The other options choose an audio track from the list of detected tracks. An easy way to set this property for a file or stream that has more than one audio track is by selecting an audio track from the Audio submenu of the Player menu.
Volume: This property controls the sound volume for this file. The default option uses the same volume as for other files. The set to option sets the specified initial volume when loading the file. The add and subtract settings will adjust the volume relative to the default setting.
Delay: This property controls delay of the sound relative to video. By default this property is remembered automatically when you use the Increase Delay and Decrease Delay commands from the Audio submenu of the Player menu. The default setting always resets audio delay to zero when the file is loaded.
Codec: This property specifies the audio codec to use when playing this file. The default setting will use the codec chosen on the Audio page in KPlayer Settings, normally auto. The auto setting will tell MPlayer to choose the codec it thinks is the best for playing this file.
