Hi, I'm exploring the possibilities of playing Multichannel files on LMS. Right now I managed to create and play multichannel flac files using 'this' (http://forums.slimdevices.com/showthread.php?19260-Playing-AC3-DTS-tracks-sourced-from-DVD) guide.
But since my complete music collection is mp3 or m4a only (due to compatibility with iTunes and iDevices), I want to be able to play multichannel m4a files. I created a file that plays perfect in iTunes / VLC, but when I play this on LMS the file gets transcoded via faad/flac and only L/R channels are played. When I manually start the custom faad binary (shipped with LMS distribution) on this file, then I see that the decoder shows all 6 channels. I have tried to modify convert.conf, without any luck. Output : Processes started when playing multichannel m4a file. Results in only L/R audio. 108 3044 10.7 0.0 2880 1088 ?
