You have selected the following audio device:

Code:

14:46:28 T:3656  NOTICE:         m_dataFormats     : AE_FMT_S16NE,AE_FMT_S16LE,AE_FMT_S16BE

That's not what i have selected in the UI (system->system->audio setup).

If you look at it you'll see it's limited to 2ch, and very poor support of data formats and sample rates. You can try selecting:

Code:

14:46:28 T:3656  NOTICE:     Device 3

That's the one i have selected in the UI...

I'll test again, but it's very odd !! I'm 100% sure i had selected this second one !

DDDamian responds: see further down your log and it shows you which device is actually selected/used by the deviceName or GUID (the long string in {}). I'm more concerned with why that nVidia only reports 2ch. As mentioned, check your XBMC and Win speaker settings, update your driver, and possibly disable the onboard VIA device.
