What is your Win OS version ? What is you Studio One version ?
Are you using the Micca G2 as audio interface both in Windows sound preferences & Studio One Audio settings ? Or something else.
Also did you checked the exclusivity options :
for windows : Open sound preferences, right click your output device, proprieties, Advanced Stats tab, try with the exclusive mode options enabled & disabled. (i have them on)
for Studio One : Audio Setup, in Audio Device tab, uncheck "Release audio device in background" (i think its reversed here, but when unchecked i can keep studio one playing when clicking out of it and can hear other medias if i play them (as long as session sample rate is still 44.1kHz as other files/medias that could be played back in parallel) .
You interface doesn't seems like a conventional one, and i don't know about it, but the issue might come from it following how it works & how its set.
Hope this might give you some leads to investigate on and that you'll be able to fix your issue soon.
