Does the Asus Xonar DG sound card work well in F14?

I'm having issues with my builtin audio. At first I thought it was the new speakers I bought. I know they're not quite as my Cambridge Soundworks but the external 5.1 decoder is having issues so I figured it was time. I hear a high tinny noise and assumed it was the cheap amplifier but after plugging in some old but nice SGI headphones I still heard it. To that end I'm in the market for an inexpensive sound card but don't want to go too cheap and get something equivalent to my onboard audio. I found the Asus Xonar DG[1] for a decent price but it uses the CMI8786 which is supported in alsa 1.0.24 (which I have) OR kernel 2.6.38, which I don't. I'm really hoping the OR is right and it's not supposed to be an AND. Interestingly enough this chip doesn't appear to have internal volume controls so I'll have to rely on PulseAudio. Anyone have this card working (well)? Even though it's not a big investment I'd like to know someone has it working. Richard
