Connect tv audio out to USB in of amplifier

Solution
If the amp has a USB DAC input then it likely has a SPDIF digital audio input too. If the TV has optical digital audio out use that. Optical and coax digital audio out can be easily converted so if you don't have a matching input/output you can make it work.
It is possible, but not likely, that the USB of the amp accepts streaming audio on the USB. What model TV and amp are we talking about?
