HDMI cord to connect my laptop and tv, sound isn't transferring to tv?

I have a Lenovo laptop and a Philips tv. I used an HDMI cord to watch movies on my tv. The picture is working perfect, I'm watching myself type on the tv screen right now…

I tried to play a video and the sound is still coming out of my laptop. I've never done this before so there might be something simple I'm not doing to get the sound to work, I just don't know what it is.YES, the volume is turned up on the tv.

Any suggestions?

Happens to me everytime.

Go on your laptop to the control pannel. Somewhere will be your sound settings. Not the volume settings, but where the sound goes. Change your default (while its plugged in) from your computer speakers to the HDMI speakers

It's a pain but… You may have right click on the little speaker icon in your task bar and on the dialogue that comes up select playback devices and change the output on there. IN most cases this will work - but not in all!

Open the control panel in Windows. Select Sound. Change the output of your sound card to the HDMI port.
