MP3 through secondry sound card??

Hi was just wondering if anyone knows how to get mp3's playing (with mci) through a secondary sound card?

i know that you can do something like this:

Code:

---

parms.wOutput = 1
rc = mciSendCommand(mciID, MCI_SET, _
        MCI_WAVE_OUTPUT, parms)

---

but that only works for wav files
:(

anyone?

Thanks in advance,
