Sorry but I have not read all the posts. Go buy an external hard drive and copy all your files to it, then plug it in to the USB on the 2i. Open the app on your phone pick USB and then pick a CD or high res file and enjoy. This way you avoid all the computer problems. HDD cost about a $100 for 1TB at Best Buy.
Plug your Toslink from the TV into the optical input converter plug that came with the 2i. Plug that into the analog input on the 2i and you can listen to the TV through the 2i.
