Thats because x265 and even newer x264 codecs will not be supported by HT. There is no sulution to it. For better audio - try prologic mode - mostly its toggle button will be available on remote.Also another annoying thing s if i play from USB in HT, 9 out of 10 videos doesn't play & saying video format not supported.
If am trying to plug USB from TV & play, the audio output s not satisfactory.
Literally it's a waste for me as of now.
Plus post photos of back of your HT for better understanding.
