Seems that I am getting clearer picture now, it is about bypassing the default to achieve another for some reasons. Thanks

if the "default" or original audio is poor, e.g. mono 1.0 or mp3 2.0, that's all u get, be it direct to tv or avr.
big media files incl iso/bdmv, 40-50gb per movie, have high grade audio like dtshdma7.1 or ddtruehd5.1, need to be "passthru-ed" by player to be handled by avr/theater system.
the issue discussed was: xbmc can't handle these highgrade audio on most devices and will just downgrade to core dolby or dts to the avr - that is correct and i think it's due to licensing/royalty payment. of course if no avr, direct to tv, it's just 2.0, will have little difference compared to mp3.
i had asked why bother to playback media files with xbmc and suffer audio grade loss when most player boxes have a native player that can do the job nicely. the answer i got is because playing via xbmc gives nice cover displays, can access subtitles - which i do not find necessary.
for online streaming, i doubt there is much dtshdma/ddtruehd material as the bit rate will be very high but there are dts or dolby material (for avr to process). of course, again, if direct to tv, that will be downgraded to 2.0.
it's all about audio - and that is impt to some people. to me, it is extremely impt if watching blockbuster movies and concerts. tv shows and b-grade movies, no need, tv audio is fine.
