Working with sound. Sound through hdmi at work

1. What is hdmi

This interface is designed to transmit data in a multimedia format . You can send analog and digital data, including audio audio. Consider the ability to handle audio through hdmi and what you need for this.

2. Set for interface communication

- HDMI adapter ;

- a computer;

- TV;

- driver.

3. Connection - procedure

• First, make sure that the output will be made via the HD2000 adapter or newer. Even for high-quality sound output, you need a shielded cable adapter;
• If the adapter from which sound is output via hdmi has a built-in output, an adapter will not be required ;
• Sometimes the chip of the multimedia connector can be integrated into the adapter. In other cases, it ends with a separate DVI output (yellow marking), for which an adapter cable is needed;
• If the adapter does not meet the standard for ATI-compliant devices, sound on hdmi will not be output. But you can use a conventional analog cord to transfer audio from the PC's output to the corresponding TV input. Modern TV equipment is also equipped with separate inputs for data "sound" and "video" ;
• For different adapters, a serial selection of adapters is completed. For example, the HD2000 series uses cable marking 6141054300G / Rev. A. The HD3000 series displays hdmi sound using a gray cable with the inscription 6140063500G / Rev. B. A gray transition cable with marker 6140063501G / Rev.A (B) is also suitable for the HD4000 standard.

4. Connected? How to adjust the sound via hdmi

After the connection, you need to properly adjust the sound. How to do it?

1. The PC sound card requires a working driver. If your computer has multiple audio adapters, set the default output to the hdmi chip.
2. You can break the sound into categories and output them to different separate boards. For example, the sound of a game or a clip from the Internet can be displayed on the main map, and viewing of movies - on a map with the output of hdmi. To do this, the media player must support the redirection of the audio stream to this interface.

5. TV and pairing settings

To sound through hdmi supported by the TV equipment, as a rule, the standard is Sound over HDMI. In other situations, in the chain of connected devices, some of them may not recognize this audio protocol. Let me remind you that in this case:

1. You can "enter" the sound through the analog interface Audio in. It is advisable to connect the audio cable to the input that is next to the HDMI connector , if there are more than one .
2. The other end of the cable from the computer to the TV is connected to the PC audio card (Audio out). This method of connection does not provide sound through hdmi.
3. Sometimes TV receivers are equipped with scart connectors . And if the source does not have the interface in question, you can always use a SCART-RCA adapter.
4. There are TVs that can not simultaneously separate sound and video from different directions. In this case, you can use (if available) a music processor, it's an audio amplifier.
5. On its rear wall you can find the AUX or RCA connector and bring the signal there.

If the source has stereo sound, the universal player usually has separate Audio in with colors: "white" - for the right channel, gray - for the left channel "incoming".

1. Also on the entrance of the muses. Player can be fed a separate cable and a video signal, if such an opportunity is present both on the center and on the PC. This signal can then be redirected to the video output for pairing with the TV.
2. For analog TVs of the old type, you can buy a special signal converter (set-top box). And already through it, having studied the instruction, to carry out the necessary manipulations.

6. Cautions and Precautions

Do everything neatly, with the power off. If the cable does not fit the specified connector, do not push it with force. Select the connectors whose connectors fit all the inputs and outputs of the mating devices.
