I'm just about at my wits' end here. All I want to do is play FLAC files gaplessly (via network preferred, but via USB is okay). The catch is that some of my FLACs are multi-channel.
I just bought an AVR-1713, and after hours of wrestling with various media servers, I have determined that the AVR-1713 cannot play multi-channel audio files streamed over the network. It treats all the multi-channel files as 2-channel only (i.e., the only available sound modes are the 2-channel ones, such as Stereo, Dolby PLII, etc). If I'm wrong about this, though, please let me know!
I thought I had finally found a solution when I formatted an external hard drive FAT32 and attached it to the AVR-1713's front USB port. I tested some multi-channel FLACs this way and heard glorious multi-channel sound! (The sound mode was automatically selected as Multi Ch In.)
But that was yesterday. Today, after adding my regular 2-channel FLACs to the hard drive, none of the multi-channel FLACs will play as multi-channel (I'm again stuck with the 2-channel sound modes). I tried everything I could think of, including resetting the receiver settings, reformatting the hard drive and including only a single multi-channel FLAC on the drive, switching to Direct mode, etc, but nothing worked. I'm actually beginning to question whether I really did get multi-channel sound yesterday, but I'm pretty sure that I did -- the multi-channel songs sounded absolutely gorgeous yesterday, and of course they sounded terrible today when treated as 2-channel (it sounded as if the extra channels were just missing, but don't quote me on that).
So am I just imagining things and the AVR-1713 is actually not able to play multi-channel FLACs via the USB port? Or is there something I'm doing wrong today that I had right yesterday?
PS: These forums were absolutely invaluable to me when putting my system together, so thank you to everyone whose wisdom I read and absorbed!
