You probably need a audio cable that runs from the pc audio out to the TV audio in. Radio shack has them so do a lot of hardware store and best buy.

Vizio M550SV no sound. Is there an audio card or does the main board have to be replaced?


See page 8 here:

From the top
- HDMI - both Audio and Video come from device via one cable.
- RF Coaxial (aka CATV) - both Audio and Video come from device via one cable.
- 15 Pin Dsub (they are calling it RGB), Video comes from this cable and Audio is from a dual 1/4" plug (looks like a headphone wire at both ends).
- Component (this is true RGB) uses RCA type cables - two sets of cables, cable one has 3 RCA at each end and they are color coded, as follows Red/Green/Blue, cable two has two RCA color coded as follows White/Red. Cable one is Video, and cable two is audio, total of 5 connections at source and 5 connections at tv.
- Composite AV - one cable set, coded as follows - Red/White/Yellow, Red/White are audio and Yellow is video.
Hope this helps.

Can't get sound to work with RBG cable from PC to TV


Sound will not work with mere RGB connection. The audio out of the PC should be conected to Audio in socket to TV.

Hello,
Your TV should have an AUDIO OUTPUT other than optic..at least " Headphones" output..
You can connect TV audio output with a RCA cable.
white and red audio jack....
since SUB has both RCA and "3,5mm Headphone female Jack"..here are the options;
** you need to buy a cable one end 3,5mm MALE headphone jack and the other end 2xRCA stereo (or 1x RCA for mono or you may need "Y cable " ) to be connected to your TV...
** or 2x RCA
white and red audio jack and connect from your TV..
**" "Headphones" output to SUB with 3,5 male-to-male cable ( the least recommended)
And you need to connect front,centre and rear speakers to your SUB as well...
Take care and if it succeeds please Remember to rate/vote and give me 4 Thumbs Up

Hello

With either the PC IN or HDMI connection, you can watch

your computer's display on the TV and hear the sound from the
TV's speakers.

When connecting a PC to the PC IN terminal on the TV, use an
analog RGB (15-pin) computer cable and a PC audio cable.

To use a PC, set the monitor output resolution on the PC

before connecting it to the TV. The following signals can be
displayed:

Format Resolution V. Frequency

VGA 640 × 480 60Hz

SVGA 800 × 600 60Hz
XGA 1024 × 768 60Hz

Other formats or non-standard signals will not be displayed

correctly.

Note:

The PC audio input terminals on the TV are shared with the
HDMI-1 analog audio input terminals
Some PC models cannot be connected to this TV.
OK.

Sony bravia to my P/C


You need to wire up the audio from the computer.
The 15 pin cable is only the video, next to the input on the tv should be a red and white phono connector which should say audio or line in, get a cable that has a headphone type jack on one end and 2 phono red and white plugs, connect the headphone jack into the back of the pc, should be the green audio out where you would usually connect pc speakers, then the phono plugs into the back of the tv and insert them into the phono ports on the back of the tv that say line or audio in. Turn the TV to PC and thats it.

hope this helps
