I have a HP Touchsmart 15 laptop and am using Windows 8.1. When I connect the laptop to the tv with a HDMI cable I have a great picture, but audio only comes through the laptop speakers - not the tv.
When I right click on the speakers icon and select "playback devices", I only see Realtek high definition audio speakers and it is already set as default. There are no other options/drivers.
Please help!
