I have the white MacBook (late 2009), the one with the thunderbolt output.
Anyway, when I plug in the thunderbolt to HDMI adapter and to my TV everything works except the sound.
I went to the sound preferences and my TV doesn't show up there.

(I also have a MacBook Pro and with the same adapter and the same TV, the sound works there and my TV does shows up on the sound preferences.)

Any solution to that?
Thanks

I PROMISE you do not have a 09 macbook with thunderbolt as it didnt exist

what you have is a mini display port.... and yes they only support video

Seconded. I used to have a 2008 Alu MB and it was displayport with video only. Now have an early 2011 and distinctly remember it was the first one with thunderbolt.

Mini DisplayPort (MDP) / Thunderbolt
Mini DisplayPort is the current digital standard on all current Macs to transfer video to an external display or TV. It has been introduced in 10/2008 with the release of the Unibody MacBook and MacBook Pros and has gradually been adopted on all other Macs.
MDP is capable of transmitting video, and since 2010, audio too. MDP is a miniaturised version of DisplayPort. It is also license free and can support resolutions of up to 2560 x 1600, which Mini DVI and Micro DVI are not able to do.
Since 2011, all Macs come with a Thunderbolt port, which is meant for fast data transfer and also as means to connect to an external display device to mirror or extend the Mac's screen.
