the audio system does not work. it is grayed out in the audio settings menu. reset everything did not work. I asked this of corporate, went unanswered. I bout another smart tv, a different brand but includes ROKU. this one has an analog audio out port like yours. do you know if the internal speakers and audio out port can both be active at the same time? the tv is a HISENSE 32h4f5. the manual does not cover this question. does yours? are the steps simalar?
