This is caused by Foobar trying to play through an audio device that is either disabled or having a driver problem. Go into File > Preferences > Playback > Output. In the drop-down under Device, you can select what it plays with, for example your sound card / interface, or you can just pick DS: Primary Sound Driver which plays through whatever Windows has as default. If other programs are playing fine, then you probably just have the wrong thing selected here.
BTW, I have found that Foobar sometimes throws this error after I update drivers for my interface until I go into the prefs and re-select it again so keep that in mind next time you run updates.
