i've tried the cable with an audigy 2 ZS sound blaster card (PCMCIA) and the cord works. i forgot to mention that i've reinstalled the driver, which made my internal laptop speakers not work, so i had to roll the old driver back. the conexant driver is listed as an SPDIF "interface" (when i go into the control panel - hardware and sounds etc.) and the audigy card is listed as an SPDIF "out", what's the difference? the audigy card works well, but it would be nice to just use my internal sound card for an spdif pass through.
