Many friends will encounter the computer suddenly did not sound or reload the system after everything else is normal, is the stereo or headphones no sound problem. I'll explain in detail the various reasons why the computer doesn't sound, and in the later part of the article, I'll explain the microphone's sound problem. Through the following detailed analysis, I believe that you can let you know that your computer is not a sound is going on, in the en

Recently engaged in the wm9713 of the external audio playback and the detection of headphones, engaged in a few days to hope that the final fix. For example, the Development Board is real210 v6.2 version number:Assuming that you want to make the external sound output, then ensure that the value of the wm9713 0x1c Register is 0x1200, the headphone output is 0x00a0, of course, the two can also output at the same time, the value is 0x12a0.Also set the Ac

I believe many friends may have encountered a computer in front of the headset does not sound but the computer behind the normal situation, because the solution is relatively simple, so has not been written out, but recently there are many friends encounter computer front headphone jack no sound, the back can be used! Ask the editor not the interface is broken, In fact, many times just did not set up a good cause, the following editor for you to introduce the computer host front

Recording and playback in the development process there are a number of problems, the main problem is three: detect whether there is a sound input device when there are multiple sound output devices, the specified sound output device detects the insertion and pull-out of headphones First, for devices such as itouch and the ipad that do not have a microphone, you need to check to see if the headset is plugged in and it's relatively easy for the iphone

Author:It168.com reny I. 3D sound effectsWith the continuous development of software and hardware, the traditional dual-channel single-layer stereo sound field cannot meet people's needs. In order to get a better three-dimensional feeling and space feeling, scientists use digital audio to generate a brand new sound-simulating 3D sound effects.In daily life, we use two ears to listen to things, obtain information from various sources, and then locate the sound through brain computing. The comput

Many people use the computer, even if the computer is used to play games, office will have to listen to music, the habit of watching movies. So a computer without sound is used to feel powerless. And a lot of people will also because I have nothing to do recently tune the audio manager. Then the headphones don't sound or there's a murmur. Our main side is to analyze the computer headphones have a murmur how

Bingo B630 Headphones are not lightweight that type, the structure will look more atmospheric, not too compact. B630 headset using the dual-power patented technology, the high and Low unit separation, can effectively interpret a more accurate and excellent sound. Headset transmission stability in the 2.4G more mature today, has been very satisfactory, the actual use, as long as there is no wall barrier, 10m distance is more than sufficient. The B63
