Laptop to TV issue

Baby_Mechanic_1

My TV doesn't play sound from the videos on my laptop, the sound comes through the laptop's speakers.

I'm sure my TV used to play the sound, so I'm wondering if I've hit a 'wrong' button along the way.

I've had a mooch in the 'Sounds' settings, but can't see anything that might help.

Any thoughts/suggestions gladly accepted.

The laptop needs to be connected with HDMI to play sound.

If its connected via  VGA cable/15 piin cable it will not play sound because that cable cannot carry sound.

And how are you conecting it?

Only HDMI would carry sound. Anything else would need a second cable. (including dvi to hdmi wither way).

My apologies - connected by HDMI.

Normally going to control panel then sound and then the playback tab will let you choose the output.

This is what I have showing when I go to 'Sounds' and then playback tab.

Select the Samsung as the default playback device.  

(When it's not connected the Speakers will revert to be the default).

That works
But why ?

Isn't it obvious?

Because Windows has always been crap at switching audio sources.

Or the more likely cause is is a driver update has come down through Windows Update and because your TV wasn't connected  at the time the computer forgets all about it and so won't switch source.
