OK here's the setup. Playstation 3 > Fiio E17 via optical cable. I power the E17 by plugging it in via a usb cable to the playstation.
Additional information. Usually headphones are plugged directly into the playstation via usb.
Now the question. Can I plug a mic into the aux jack on the E17, configure audio setup on the playstation, and be heard in a game?
P.S. I know that there are some headphone brands out there that come with their own mic and mixamp. But. I'm not sure how they work.
