OpenELEC Testbuilds for RaspberryPi (Kodi 16.0)

Assuming you are connected via HDMI and your A/V receiver supports multichannel PCM (almost certainly does if it has HDMI inputs), then there should be no difference.
One way Kodi decodes the audio, and the other way the receiver does. Passthrough is good for Pi1 where CPU is weak, but Pi2 doesn't have a problem with decoding audio.

The advantage for disabling passthrough is kodi is able to resample the audio when the audio/video clocks needs adjustment
(live TV may require this as the clock of the backend is likely to be different to the clock of kodi, so a small amount of clock drift needs correction).

dvdplayer used to correct clocks with passthrough in a slightly ugly way of duplicating or dropping whole packets. That could result in audio glitches.
videoplayer no longer supports drop/dupe of passthrough audio.

So, options are to disable passthrough (allowing resampling), or disable "sync playback to display" which means audio is perfect but you may get video frame drops when clock adjustments are required.

Personally I'd disable passthrough.
