If you want to use dmix, change it to resample everything to 96kHz (or higher) rather than 48kHz. There is a 'rate' parameter for this. Alternatively just output directly to the hardware device (hw:0,0) or similar. If you're having problems with mplayer, Audacious will playback high resolution files nicely.
