A:AnswerOk? This is a statement rather than a question. Judging on the age of this “question” I assume you have returned it? If not, that is what I suggest.
A:AnswerYes this TCL HDTV is wall mountable. You'll need a wall mount compatibile with vesa 200mm X 300mm mounting standard which is so common any walll mount that supports a minimum of 25 lbs and a 55 inch screen should work just fine
A:AnswerThere is a 3.5m jack on the left side of the TV to connect an external speaker.
After re-reading your question, I deduced that you might have already connected a speaker but cannot get it to produce sound. There are audio settings which can be accessed through the controller in which you can change your audio output. It is not difficult to find.
A:AnswerTCLs Q5 Class supports powerful new HDMI features, including eARC and an Auto Game Mode (ALLM) with AMD FreeSync assuring not only fast gaming response, but also a great cinematic picture that gamers demand! Hope this helps! Thank you, TCL Customer Support
