I know the PBO supports several different audio formats. When playing back an audio file (flac, wav, mp3), does the PBO output the audio as lpcm regardless of the original file format? I'm asking because regardless of what I played on my PBO via hdmi, my 3.5 year old receiver was able to work with the signal and play it back even though the avr's manual makes no reference to flac, wav, mp3.
Any info on this subject would be appreciated. Thanks.
