Hello,

I just bought a Mini DisplayPort to HDMI cable, to connect my MacBook Pro (2.53 GHz Intel Core 2 Duo, 4 gb 1067 MHz DDR3) to my Samsung UE 37c6000 Full HD LED TV

It does connect and looks great, but my sound isnt working, so I can see it on my TV but it still uses the soundboxes of my MacBook Pro.

How can I fix this?

Plz help me,

Djef

The C2D 2.53 MBP does not provide audio out over it's mdp. You will have to use an audio cable.

You can read through post #3 in the following thread to learn how to do this with your TV.

If its a mid 2010 macbook pro it should support audio right? I have a 2.4 with C2D and it works fine. Could be an issue with the adapter you're using considering some wont work (I have a dynex I got for $20 and it works fine). What I had to do was connect the second display with minidisplay port to hdmi, then went into system preferences/audio/output and selected hmdi for output of audio. Now whenever I connect the hdmi cable from the tv to minidisplay port the mac automatically switches to hdmi for both video and audio. Its worth a shot to try it.

Yes, all of the mid 2010 models do output audio over the mdp.
