Many users who use the MacBook have encountered internal speaker failure, and the MacBook's built-in speaker fails, and its headphone holes will also light up red, as shown in the following figure. So what causes the MacBook's headphones to Kong Liang the red light? What should I do if the MacBook speaker doesn't sound? Here's a look at the solutions offered by users:
To solve this problem, we have to consider two kinds of situations: Dual systems and non dual systems, the Netizen said.
1. If your MacBook is already loaded with Windows via the Bootcamp software, the speaker does not sound and the headphone hole lights up the red light, which is basically due to the incorrect driver version, We only need to reinstall the correct version of the Bootcamp driver to solve this problem.
2. And if your MacBook is a problem with the OS X system, then let's give you a brief account of the cause of the failure:
The Apple has a mechanical switch in the MacBook's headphone jack. Normally, the mechanical switch will be turned on after we plug in the headset, when OS X will know that the user is using the headset, and then shut down the built-in speakers and switch the sound signal from the headset. When we unplug the headset, the switch will automatically go to the shutdown state.
Let's take a look at the comparison of the systems plugged into headphones and not plugged into headphones:
▲ Insert Headphones before
▲ after inserting headphones
In that case, why does the speaker have no sound? In fact, the mechanical switch inside the headphone hole can not be automatically closed for various reasons, the system will think that the headset has not been unplugged, this is the root cause of the speaker failure. Coincidentally, the Apple headset also supports fiber audio, which emits the red light when an external device is plugged in to turn on the fiber audio input/output device.
Since we already know that the mechanical switch is the culprit, so long as it enters the shutdown state, the speaker failure situation can be solved. And to turn off the switch is actually very simple, a toothpick and the like of fine items can be easily handled.
We need to try inserting the toothpick into the headphone hole, gently try different angles and positions, and then you will feel that there is a place to be blocked, that part is the mechanical switch, find the right place after a touch, red lights will be extinguished, that is, the switch has been closed, the speaker back to normal.
