The computer is connected to the DVI to HDMI line connected with the TV, no sound

Recently saw some people find television picture but no sound problem in asking the computer to use DVI to HDMI cable connected with the tv. The reason for this situation is because the DVI interface can transmit audio signals, converts the HDMI signal after only a video signal, so the ultimate cause of TV without a sound. Someone tried to use 3.5-3.5 or 3.5-2RCA audio line to external computers and television, but in the end, also cannot let television sound.

The paper analysed the causes about this situation, found to be due to some computer graphics of old, with no built-in sound card card, cannot the card through the transmission of audio, computer chassis with only DVI interface without HDMI interface, so in the connected TV with DVI transgenic HDMI line, there will be no audio.

Some people think that use the audio line to connect the TV can make up for the defects of the missing audio.

On the TV set the PC audio input, TV is still no sound.

This is because the television input signals into the HDMI interface as the default video and audio input, will ignore the signal input of the other, will not be able to use an external audio line.

(PS: use HDMI to DVI cable condition is not the same, this case can make TV sound through the audio cable television. Because the television connecting interface is DVI, the TV will not be the default audio input, also can use external audio signal.)

To at present the graphics caused no audio output is not the right solution for the problem, only through the computer external sound or change into a HDMI interface with the built-in sound card card instead of solving the problem of. For some of the current mainstream television, are used with a HDMI interface of the HD display, thus updating computer hardware is also represent the general trend, and more easily compatible with mainstream HD tv.
