Media server help
So, I want to stream music mainly to my Nexus 7 and iPod, I need to be able to access my external HD where all my music is kept and select by the music from the pads. It must support flac, since 98% of my music is in flac format and I loath to convert them all. I have at my disposal a Roku 2 and a Roku 3, a Sony Google device and I'm getting a Rasberry Pi in the next couple of days as well. I would rather not dedicate a full blown PC to this.
Right now the HD is connected to a Oppo 93 where I can access in the home theater. Oh, yea must be simple enough for my GF to access it as well. Suggestions?
