how to send audio from pc to tv
I'm planning to send audio from my old pc (win XP) to a TV.
The TV has the standard yellow coax looking plug. My pc has a small NIC card in back with line, speaker, and audio. The audio plug uses a small pin plug. No other audio output things on the frame. If I find a cable to hook these up, will that be OK on audio? If not, what a good choice for a NIC or some other way? |

NIC is an acronym for _N_etwork _I_nterface _C_ard. That doesn't really hinder my comprehension of your questions, but I thought you might like to know what it means as it will probably affect how you use it. "standard yellow coax looking plug" also seems a bit confused. If it's a standard yellow *RCA* plug, like this: http://library.noctrl.edu/instructio.../elmo/tvin.jpg ....then we're good. You might not have a red and white audio input if it's a older set, some of them will just have a white audio and a yellow input. Either way, it will work. "coax," would probably require a little extra, it looks like this: http://www.bv229.k12.ks.us/bvnw_lmc/tvcoax.png I'll just assume it's the first option--the RCA plugs. You'll be able to feed the audio input(s) with a line out from your aforementioned sound card. It sounds like "audio" might be "audio out," and suitable for the purpose. Can you maybe find a picture of what those various connectors on your sound card look like? As for the video part of the signal, you'll have to have a device to make that output--typically the video card. Video out used to be fairly common with medium to higher end cards, but that's sort of gone in the crapper with the popularity of onboard video. Does your monitor attach, on the PC side, to a card or to the motherboard directly? If it's attaching to a card, are there any other connectors on that card? Assuming that you don't have a suitable video card with an output, your most economical option is to buy one that does. I notice that those cards are not so popular anymore, but if you tell me what mainboard you have, a suitable card can probably be found. Your system might even see some performance boost for your efforts. You can use a tool like Everest Home Edition to determine the motherboard, or you can unplug the PC and look inside. Use google to make sure that the Manufacturer and Model you are reading from the motherboard are in fact legitimate model numbers, and not just some sort of other identifier. |

The audio plug uses a small pin plug. No other audio output things on the frame. If I find a cable to hook these up, will that be OK on audio? If not, what a good choice for a NIC or some other way? The first thing you do, is positively identify what the jack is on the TV set. TV sets use a standard coloring scheme for at least some of the jacks. Yellow RCA jack = composite video only White RCA jack = left audio channel Red RCA jack = right audio channel On the TV set, you may see the three of those clustered together. The fact that the audio and video have separate jacks, tells you the standard for the yellow jack, doesn't carry any audio. Some TV sets have no provision to send them audio. Mine, for example, requires that I use my stereo to carry the audio portion of the program. There is only a composite video jack on the front of my small portable TV set. To connect to a particular TV set, I would need two things. 1) Composite video output from the graphics card. On the graphics card, there may be a "TV" output. It will be a black, circular DIN connector, with room for multiple pins on it (4 or 7 or 9, it varies). Again, there are standards that are roughly adhered to. Four particular, symmetrically placed pins on the outside circumference of the DIN connector, yield S-video (Y, C, GND, GND, carrying luma and chroma). An adapter, converts from DIN pinout, to an RCA jack. That RCA jack is what would be connected, via 75 ohm video coax, to the yellow jack on the TV. Note that you cannot use audio cables for this one - the cable must be specifically for video. The key ingredient is "75 ohm" and "coax". 2) For the audio, that comes from the sound card. The sound card may have three to five 1/8" stereo jacks on it. Again, there are color standards, and green is usually the "Lineout". To go to the TV set, you need a 1/8" stereo plug on one end, and two RCA female jacks on the other end. You can use a pair of audio cables with RCA males on each end, to connect to the TV. For cables, you can either use video rated cables (can be used for video or audio), or audio cables (good enough for audio). For audio, the cables don't have to be "75 ohm" or "coax". If you were stuck on a desert island, and had only zip cord (appliance two wire cord) and male RCA plugs, you could make acceptable audio cables for carrying line level signals. So the signals come from two separate cards on your PC, and have adapters needed for each. ******* For video: This is the DIN pin pattern for S-video. http://www.tkk.fi/Misc/Electronics/c..._connector.gif This one is DIN S-video to composite - yellow colored to go to yellow TV jack. http://www.sandberg.it/img/prod/lg/502-34_lg.jpg This is the "bullet" version of the same adapter. It is more compact and these sometimes come with the graphics card in the box. http://www.tvcables.co.uk/images/items/AD009.jpg ******* For audio: This goes into the green Lineout on the sound card. There are two RCA jacks on the opposite end. One jack is "white" for "left audio", and the other jack is "red" for "right audio" http://www.radioshack.com/product/in...ductId=2103225 Radioshack wants a fortune for cables, so I might shop around for them. Finding "Monster" brand cables in their store, is not exactly good for the customer's pocketbook. One way to make cables, is to get coax cable with the thin wire in the center of the connector. The connectors on the end are threaded. Usually that kind of wire is cheap and commonly available. You can stick one of these on either end of the cable, to convert to RCA format. "F" Connector to RCA. http://www.radioshack.com/product/in...ductId=2103580 Also, in the video description above, the TV set could have a DIN connector (black, with four pins), and if that is the case, then an S-video cable could be used, instead of the DIN to RCA adapter. In that case, the cable carries S-video (Y,C,GND,GND) from the video card, right to the TV set. Expect that cable to be suitably overpriced as well. There are other standards for TV, now available on new LCD TV sets. Some of those are easier to connect up. But on the computer end, support is still far from perfect. There are only a few computer graphics cards, with fully featured HDMI. A proper HDMI output now, carries both digital video and digital audio, so separate cables are no longer needed. Only one cable to do the whole job. But many early computer HDMI connectors lack the audio channels. For a lot of people, audio still has to be solved separately. Paul |

Ok, I just noticed the "audio" in your subject line. You can disregard the part about video if you only want audio. That sort of makes the use of a tv a bit weird. Can't you just pick up a pair of cheap speakers? |

Here's my TV. The jack in front, low down, on right side is the audio, and
is a phono yellow and white plug. http://www.symphonic.us/pdf/spec/1999/SC3919.pdf I'll make up a cable with pin plug on one end and the phono plug on the other. |

The yellow socket is a video input. Audio inputs are red and white. |

I guess that means the audio in, is monophonic. The owner's manual here doesn't go into details, but that would be my guess. http://www.symphonic.us/pdf/om/SC3919.pdf For best results, you'd need a way of feeding a mono signal to the TV set. If the source is stereo on the computer, that means a way is needed of blending it down to mono. There may be a clever software way to do that. Or the alternative is to use some sort of adapter. Basic blending would only need a couple capacitors inside the adapter. There is a stereo to mono adapter here, but you can never tell from the sparse description here, whether Left and Right are blended into one signal, or simply one of the two channels are selected. You'd hope each channel would be capacitively coupled to both output contacts (tip and ring). Plug this to Lineout, then next plug your dual RCA to 1/8" plug to that, and then in theory, an RCA to RCA cable to the TV white jack should complete the job. http://www.radioshack.com/product/in...ductId=2102690 The reason for continuing to buy a 1/8" stereo to dual RCA, is for the time in the future, where a newer TV set has stereo RCA input.

The audio input line is etched on the set, and is yellow.
Many thanks to all. I will figure out how to get mono to TV. Shouldn't be a big deal. |
