I just brought a 32"Sony Bravia LCD today and rying to get the Comp hooked up - managed to get the video easy as but audio has me stuck.

I went to Jaycar and he gave me some crazy plug that dosen't work.

Then went to dicks,ith and they gave me a long cord with a headphone size jack and each end - that dozsen't work, and I have a headphone jack kinda plug with that White and Red RCA type cables at the bottom which dosen't work either.

Anybody got any ideas or know a soloution??

Below are some pics I took of the inputs on the tv so you can see what im workin with.

thanks

What you need to look for is a PC input, normally you will have a VGA input, and there will be either a 3.5mm socket next to that, or two RCA's.

If there is not, consult the manual and see if it talking about a audio input for PC's. It looks like their is a 3.5mm jack underneath the VGA connection.

So you will need to to from the audio out/headphone socket on your laptop, to the 3.5mm socket under the VGA cable.

you will need to use 3.5mm to 3.5mm to go to the PC audio in which is just below the VGA socket. Also you may want to check the setting to ensure the PC -in audio is enabled on TV, and do a sound level test in case the audio level output from PC is too high to the TV, otherwise your speakers will blow.

I was using the 3.5mm Headphone jack instead of the PC input LOL

Another thing that now I have it up and running all the system sounds that my comp makes like the humming of the processor etc.etc. seem to be coming from the TV instead of the comp - whihc I thought was strange i didnt think they came thru the speakers.

thanks for all your helpi - much appreciated

Onboard sound is rubbish, get yourself a soundcard or USB sound device if you cant get rid of the noise, just make sure that you have the master and wave volumes on the PC up loud, and turn all the others down and mute them in the mixer since the microphone input is usually really noisy, as can be the internal cd audio header since its usually located well away from the audio codec.

If its still noisy, then just accept that the 20 seconds they spent adding audio to the motherboard with no regard for shielding or circuit layout was not long enough and spend money on a decent audio solution.

Onboard sound is rubbish. But then considering it's a laptop, don't expect too much.

If the sound is becoming a major issue, consider investing in something design to do the job properly.

Donkey, wiggle the audio plugs too, esp the one plugged into the tv, as sometimes you can get hum induced by simply having a dodgy connector. Also try playing something plugged into another device - speakers p'raps ? - to see if the hum is being generated leaving your laptop, or if the tv has something peculiar with it.
