I am trying to use my TV as a monitor and sure my TV speakers because the speakers on my laptop are garbage. I bought a display (which to my knowledge carries audio) to HDMI adapter. My laptop recognizes that the TV speakers are there and I set them to my default priority speakers, I have tried disabling my laptop speakers and the headphone jack. I've also updated the drivers and windows (7) to their latest iterations.
If more information is needed please ask and I will do my best to supply you with an answer.
