You are positive that there was a sound option for the HDMI?
Sometimes sound is not supported through HDMI,
You could also try restoring to a point where everything worked
I have a HP Pavilion Entertainment PC (it's a laptop), model dv6-1128TX.
I used to be able to connect my latop to my TV using a HDMI cable perfectly, until one day I disconnected the HDMI cable and I couldn't get sound back through my laptop. My father played around with it, and ever since I can only get a video on the TV and the sound comes through my laptop speakers.
There is no where to choose the HDMI sound option. either. There used to be one, but after my father did whatever he did to my laptop the option is no longer there.
Does anyone know how to fix this?
