Problem: When using an HDMI cord from my HP Envy Touchsmart Ultrabook 4 (4-1105dx)to connect to my TV to view movies, the video appears on my TV screen, but there is NO sound from the TV. Instead the sound comes from my lap top.
Troubleshooting: I have looked under Sounds in the Control Panel, but the only choice listed is Speakers & Headphones IDT High Definition (which is the default) and does not allow sound from the TV when using the HDMI. I have also tried to download Driver and Audio Graphics, but wasn't sure which one & the ones which were downloaded have not solved the problem.
Can you assist me? Which is the correct Audio/Graphic Driver to download? Or is there another possible reason why I cannot hear sound from my TV when using the HDMI to connect to my lap top?
