hi, I think it's better post here too what I found. my configuration:
- zotac HD-ID11 ION2 > usb > fatman amplifier iTUBE mkII with DAC on board **
- openELEC 3 RC1
the system is also connected via HDMI to Samsung TV
** dac reported with lsusb:
CM102-A+/102S+ Audio Controller

first, sound is distorted. volume is very high, as I little turn up on ampli it sounds very loud. music is not clear, fat and compressed, it seems that signal input is kept in clipping.
with the same hardware if I boot in windows 8 instead openeELEC and launch xbmc in wapasi mode > usb, everything is near right. it doesn't reach the excellence of foobar (there's lot of difference, but is OT), but acceptable.
I boot into openeELEC again and sound is horrible, but what is strange is that I lost left channel too!
I thought that was ampli fault but didn't.
I found instead that if I boot openELEC with volume of TV>0 the left channel via usb dac is mute. I tried to reboot with TV volume at 0 and left channel turned on, retried with volume up and it turned off!
this, with the fact that sound is very distorted, make me think that there's some interation across outputs.
but, in fact, I have no idea, I only thought that it could be a kind of thing that you coders would to know; of course I hope that I'll resolve my issues too.
