Computers are increasingly using digital video instead of VGA. Many computers now have a DVI connector in addition to the standard VGA connector. DVI carries digital video and happens to be the same signal format as used in HDMI cables. Using a DVI to HDMI cable allows most modern televisions to display the computer screen. There is one large difference between DVI and HDMI in that DVI connectors do not carry audio. If the computer has a DVI connector, there is definitely no audio carried. If the laptop has an HDMI connector, it may be the case that it still carries no audio. Some computers use HDMI as the video connector to save space but retain the DVI signal format, missing the audio signal completely. If this is the case, all is not lost. Most televisions that have an HDMI input also have an analog audio input connector linked to the same input. The setup menu normally allows a selection of digital audio (using the HDMI cable) or analog (using the analog connectors). If there is more than one HDMI input the analog option may be on just one connector. If this does not solve the sound problem, there might be a problem with the audio output on the computer itself. A search through the control panel help to eliminate the problem.
There has been a trend in recent years for computers to use digital video outputs such as DVI. As laptops become smaller, DVI connectors have been replaced by HDMI connectors which are essentially a compatible interface. The difference is that DVI has no support for sound whereas HDMI carries sound as well as video.
Some laptops have had an HDMI connector fitted but configured as a DVI port, namely to carry video without audio. If this is the case, there will be no sound received by the television.
There is another possibility, related to the DVI / HDMI compatibility issue. A PC with a DVI port can make use of a DVI to HDMI cable to connect to an HD television. As DVI has no sound, many televisions feature a 3.5mm jack socket that can be used for sound from the PC. If the 3.5mm jack connector is enabled, the audio on the HDMI input will not be used. A check of the video or audio input setup on the television may well allow the analog 3.5mm jack to be turned on and off.
Finally, it is worth checking the PC configuration to make sure the audio is actually routed to the HDMI port. For the same reasons, many PCs will allow the audio to be routed to an analog output instead of the HDMI to allow a DVI display and a separate audio input.
No. The only cable that transmits audio and video is HDMI.
An optical audio cable is used to transmit digital audio (AC-3) signal from the source to the receiver, such as from a DVD player to a digital audio amplifier/receiver. You can transmit 5.1 dolby digital or DTS surround sound with an optical audio cable, same as digital coaxial audio cable.
No, a S/PDIF is, by definition, a Sony / Phillips Digital Interconnect Format connector, and is always a digital signal. It is usually connected by an RCA cable, and can be carried by cable specified for analog use, but digital cable is better.
An optical cable is a plastic or fiberglass wire that transmits digital audio from one device to the other.
The audio cable has nothing to do with DELAY. If you have delay, it is caused by something else.

No!
The RGB cable is VIDEO only, get the AUDIO from the HEADPHONE jack on the computer.
No I tried it on
If you want to have internet on that laptop you need to be connected to internet provider which usually happens directly (connected to the modem) or indirectly (connected to the modem through wired or wireless router).
You would need a red, yellow, white audio video cable.
yes, if the little block/pin on the PSP end will fit into your laptop it is absolutely safe to use it as a video/audio cable. THANKS!!
If your laptop computer is only connected wirelessly, then the only way to dial a phone number is with a VoIP application or service, such as Skype.
The cables that do that are HDMI, Displayport or coaxial cable (antenna) wires.
It really depends on the connection types you have on your laptop and projector. If your laptop and projector have HDMI connections then use this for the image and audio. If not, the next best would be DVI for the picture and then whatever audio connections you have (analog stereo mini jack possibly). If you don't have any digital video connections then use the VGA for the image.
