Quick version: the power LED is not coming on and no sound is being output. Long version: The delta was purchased years ago. It was working fine for a year, then stopped working. After sending it to maudio, they found it worked fine. Turned out the drivers stopped working. I reinstalled the drivers and it worked like they said. Since then, I recorded with it for many months, then packed it and stored it indoors at room temperature. I recently setup again. New XP system, 5.1.0xxx drivers installed fine. No errors in control panel > system. Using known good audio cables. Power outlet is warm. Assigned multiple Delta channels as main audio device (1/2, 3/4, etc). Played sound with windows sound and winamp with delta channels. Delta control panel shows output signal on whatever channel I assign. The power LED is not coming on, the delta breakout is not getting warm, and no sound can be heard either with headphones or speakers. I believe the delta1010 is not powering on. I emailed maudio about this a moment ago. My questions are: 1) is there any other testing I can do? 2) has anyone had this problem before?
