macbook on tv via minidv to hdmi - no sound?

frugalsar

Hi,
I'm trying to hook up my macbook to my TV (a 60inch LG full HD) so I can watch my movies through it, I bought a minidv to hdmi cable from ebay and have a brilliant picture but have no sound through it? I then bought a headphone jack to Audio (red and white) and tried that but that doesn't work either! What am I doing wrong? How do I get sound?

what type of movie file are you trying to watch? you may not have the right codec - try Perian perhaps?

I'm playing .avi and .mkv through Divx, I have no problem with playing the sound on the mac? it's just when I hook up to the tv?

What mac book do you have? only the ones produced in the last 2 years have Audio on the HDMI connection.

If you do you'll have to change the audio output to Digital HDMI rather than analogue.
If you have an older Macbook then double check the audio settings.

it's an older macbook, 2009 I think! also there's only 'internal speakers' on the audio settings?

With the right format it can be played.
You may have a check for the right size and format for your TV set.

I dont think its the format as itunes and internet video have no sound too?

It's not the video thats at fault.

What Model TV do you have?

OK everyone STOP with codecs and TVs.
The macbook has a Mini DVI out. This doesn't carry sound!
OP do you have a surround sound amp or anything? You've got the picture right, but you want to EITHER:
add a digital (if supported) or analogue 3.5mm headphone jack into the headphone socket of the Mac, and then into either an optical or phono input on the amp, as you've attempted on the TV.
OR if you don't have an amp, you need to have a look at the back of your TV and look for a PC input - DVI preferably (rectangle) or VGA (blue). Using one of these, plus a PC sound input on your TV (phono or 3.5mm) will let you use the sound from the Mac.
Your current problem is that with HDMI, the TV is assuming it's getting sound and pic through it, so doesn't offer any other inputs.
