I finally took the plunge and built my own rig. Everything worked fine until I plugged my Boston Acoustic Digital BA735 speakers into my EVGA 680i motherboard’s onboard outputs: Nothing happened. I received no sound at all. I tried the same speakers with a Creative Sound Blaster X-Fi XtremeGamer card and got the same result: zilch. Am I missing something here?
The BA735s can’t be used as digital speakers—at least not with your hardware. The Sound Blaster X-Fi XtremeGamer supports optical out, not coaxial digital audio. And your EVGA 680i also supports only optical SPDIF out. The Doctor believes that the BA735 speakers support only coax SPDIF in for its digital mode. You can’t run optical digital-out to a coaxial input.
Fortunately, the speakers have an analog port. You should buy a standard 1/8-inch cable and connect the analog-in port on your speakers to the green audio-out of your soundcard or motherboard.
