Flac suport

Hallo this is here in site:
Are multi-channel AAC and FLAC supported?
Yes! Infuse will pass these formats as multi-channel LPCM

But music files “flac” files not work, why?
Thanks

At this point free-standing music files are not supported in ANY format.

My guess that adding support for free-standing Audio files is likely to be a feature that might be something that will come eventually but will not be before the next major version of inFuse (v6) or later and for which there is no ETA.
