I posted this in Fiio forum. But I don't get any traction there. So I decided to post it here.
I did a test by downloading a sample multichannel PCM from http://www-mmsp.ece.mcgill.ca/documents/audioformats/wave/Samples/Microsoft/6_Channel_ID.wav . I encoded it as ALAC and FLAC. I tested them in PC with foobar2000. All channel sounds right to me.
However, when I play them back in Fiio X3II with firmware 1.4:
1. ALAC is a total disaster. I can hear all channels from my headphone but all channels are mislocated.
2. FLAC is a mess, too. It handle front left and front right correctly. But I don't hear rest of the channel. I beleive it didn't down mix multichannel.
3. PCM is acceptable but missing subwoofer channel.
I think this is a serious bug in Fiio X3II player when decode multichannel files. The specs claim it can play all sorts of lossless format. But it failed to meet this specs.
