Couple of questions related to the Shield (apologies if they have been answered, I could not find). I plan to connect the Shield TV to my TV through HDMI and was hoping to use USB audio to connect to my Sonos Play:5.
1. Is this possible - delivering video through HDMI and audio through USB?
2. Also, what is the best way to obtain 3.5mm output from the USB port?

Thanks a lot for any guidance.
