I have a problem with my DDDAC1794. Actually probably I don't but I thought I'd throw this open as someone here may know how it can be sorted .

Okay so I built the DAC a few years back and it has worked flawlessly ever since. I use it sporadically (I'm a vinyl sort of bloke) and keep it powered off. I have a comp running Windows 7 and have foobar.

This is how I remember the sequence of events. I wanted to use it yesterday but after powering it up I could get no lights to work. I fiddled about with it and re-installed the latest driver I had (V2.23.0) and the DAC came to life. To all intents and purposes it looked fine however there was no sound. I have checked W7 and it all looks fine, everything is 100% volume and nothing muted and the settings for foo match with those in the guide. The question is have I missed something obvious. Nothing had been changed since the last time I used it - the comp is a stand-alone music pc and as stated previously, rarely used. Any ideas to test if it is a software problem with the PC or if it the DAC itself?
did you try spdif? or do you have any means to check the I2S signals?
Happy listening and building
