I just got my digi+ I/O the other day and made it work rather quickly. I use it as a 2 in, 2 out DSP processor for my headphones. The input is Chromecast Audio over optical SPDIF. It all works fine for a listening session, but when I stop casting for a longer period of time, like overnight, the hardware locks up and I can't simply start playback where I left off. Shorter periods of inactivity seem to be OK. Is there a software switch/setting that I need to look at?
Digi+ I/O keep active?
