|colspan="2"|'''Number of channels'''
|Select the number of channels supported by the audio connection, or the number of speakers if connected by analog connections. This setting does not apply to passthrough audio. Note - Number of channels is expressed as the number of PCM channels that the audio connection support, so although SPDIF only supports 2.0 PCM channels it can still output multichannel 5.1 audio using a compressed format such as Dolby Digital.

'''[Enabled]''' maintains the dynamic range of the original audio source when downmixed however volume will be lower<br>
'''[Disabled]''' maintains volume level of the original audio source however the dynamic range is compressed. Note - Dynamic range is the difference between the quietest and loudest sounds in a audio source

'''[1- 10 Minutes] -''' same as Always except that after the selected period of time audio enters a suspended state<br>

|{{redv|'''IMPORTANT NOTE:'''|
The "'''capable receiver'''" options relate only to the '''passthrough''' of audio to another device such as an AVR, where that device must support decoding of the format. Before leaving any "'''capable receiver'''" option enabled check to make sure that both the playback device running XBMC (e.g. HTPC) and the connected device (e.g. AVR) both support that format.
 
If you have a "'''capable receiver'''" option enabled that your device does not support then this will result in poor playback of video typically with a very low frames-per-second and no audio, so for example if the '''TrueHD capable receiver''' option were enabled then make sure that the playback device can passthrough TrueHD and that the connected device can decode TrueHD, if either of the devices do not support TrueHD then the '''TrueHD capable receiver''' option '''MUST''' be left disabled.
 
For any format where the "capable receiver" option is not selected, XBMC will still playback any content containing those audio types, however instead of the audio being passed through, XBMC will decode audio and then send the audio in a compatible format.
 
If connected directly to a TV be aware that TV are not compatible with DTS, TrueHD or DTS-HD, typically the only encoded format a TV will be compatible with is AC3.}}
