I have Audiotrack Prodigy Cube. I'm using this card with my HTPC and Linux Ubuntu 13.04 and XBMC (software media player and entertainment hub for digital media)
When I playing FLAC or MP3 music ....sound is very good :)
Only I see problem with playing movies... After some time of playing ... i hear cracs? noise ... only on left channel.
I have Prodigy Cube connected to my amp by RCA cables.
I don't know that I have good configured Audio Output. Maybe someone can help me?
Should I choice Digital Audio Output or Analog Audio Output?
Here is the link from XBMC wiki page.
I know that You don't have support for Linux Users ... but many people using your product under this system :)
Also as I wrote ... the music quality is amazing ! :) I'm very happy that I bought this card.
Only what I need is help with properly configuration audio output.
Here is a screen with Audio output options
