Ok so I have Hisense 50K321UW TV and an Edifier S760D. My plan is to get an Android box, install Steam Link Android(the most recent version adds 5.1/7.1 audio) on it to stream my PC games in the living room. Now I believe most Android boxes are not capable of converting 5.1/7.1LPCM audio through SPDIF.
So will an item like this help:

Also do places like Lowyat or Digital Mall sell these items?
