How does acoustics have electric current sound to do
Method 1: Check whether the [audio line] interface is properly plugged in, connect it with the green audio interface of the computer through the [audio line], and the pink interface in the sound card panel is usually used to connect the microphone, if the wrong connection, the sound will also send out a weak sound of current.
Method 2: check the power supply is correct, through the case of audio equipment are marked with rated voltage, too high power supply voltage will lead to sound internal current sound. When necessary, the voltage regulator can be used for power supply or voltage stabilization through electrical equipment.
Method 3: part acoustics appear "power supply" and other noise phenomenon is caused by improper software setting. To solve this, you can take the following method: open the "Control Panel", click "Sound and Audio" -> "Manage Audio Device" item to enter.
Method 4: Electromagnetic interference can also lead to the sound of electric current. In this way, mobile phones, microwave ovens and other easy electromagnetic equipment can be far away from the sound to effectively prevent the production of electric current sound.
Method 5: Switch to the "Play" TAB, then select "Player" and click the "Properties" TAB to enter.
Method 6: In the window that opens, switch to the "Enhance" TAB, check the "Disable All Sound Effects" TAB, and finally click the "OK" button to complete the setting.
Method 7: if the above method cannot solve the problem, it is probable that audio hardware itself appears malfunction, can send maintenance point to undertake maintenance only.
