No Input and No Output Devices Found on MacBook Retina 2015

Hi Guys,

I have a MacBook Retina Early 2015 A1534.

I was using it as per normal and shut it down. The next day I turn it on to use it and there isn't any sound through the speakers or headphones.

I check the sound properties, and it says: No output devices found. It also says No input devices found.

I reinstalled the OS X Yosemite, and that did not fix the issue.

Wouldn't you know it, but it is out of warranty by 2 months.

Do you think that the following part may fix the issue:

MacBook 12" Retina (Early 2015-2017) Audio Board

Thanks heaps,

Daz

最有帮助的答案

First, disconnect any external audio devices from your computer. Also disconnect any cables from the USB, FireWire, or 3.5mm audio ports.

From the Apple menu, choose System Preferences.

Select Sound.

Click the Output tab, then select Internal Speakers. If you don’t see Internal Speakers as an option in the Output window, contact Apple Support.

If the volume slider is set low, move the slider to the right and test again.

If the Mute checkbox is selected, deselect it and test again.

Back up all data before making any changes.

1. Start with the above recommended steps. Don't skip any of the steps. It's the starting point for further efforts to solve the problem.

2. Make sure you have a fully up-to-date installation of OS X.

3. If you've installed an application called "Memory Clean" or any other third-party software that is supposed to "clean" or "purge" memory automatically, remove it according to the developer's instructions and restart. You should do that even if the software is not causing the problem, because it's useless.

4. Other third-party software that has been reported to interfere with sound output includes "Boom" and "Samsung Kies." If applicable, uninstall according to the developer's instructions (not by dragging something to the Trash.)

5. If an AirPlay device is selected for sound output from iTunes (or from other applications via third-party software such as "Airfoil"), deselect it.

6. Launch the application "Audio MIDI Setup" by entering the first few letters of its name in a Spotlight search and selecting it in the results (it should be at the top.) Select Built-in Output from the list on the left. If the Mute boxes are checked, uncheck them.

7. If a red light is visible in the audio-out port when sound should be playing, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. If not, the machine needs to be serviced. Inserting any kind of tool in the port may cause damage that won't be covered by the warranty.

If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.

8. Disconnect all wired peripherals except keyboard and mouse, if applicable. If more than one display is connected, disconnect all extra ones. Restart and test.

9. If you have a MacBook Air, turn off Bluetooth and restart.

10. Start up in safe mode. Don't log in; just restart as usual when the login screen appears. When you do, make sure the words "Safe Boot" do not appear in the login screen. If they do, the system is still in safe mode and sound won't work.

11. Reset the NVRAM.

12. Reset the SMC.

13. Triple-click anywhere in the line below on this page to select it:

/Library/Preferences/Audio

Right-click or control-click the highlighted line and select

Services ▹ Reveal in Finder (or just Reveal)

from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash. Recreate your settings in the Sound preference pane.

*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select

Go ▹ Go to Folder...

from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.

14. Reinstall OS X after backing up all data.

15. Make a "Genius" appointment at an Apple Store.

This could be helpful to you but, how much I can't say, you can gain more information from the Linc Davis Post

Hi,

Thanks very much for the reply.

I have in fact done all this.

I have read the Linc Davis Post.

I did take it to an Apple store, and their technician tested it and said the sound board had failed. He quoted me $322.00 to repair.

I am not paying that much, so I was going to order the item and replace it myself.

I was asking in post if this was the sound card for my model?

Did you happen to swap out the audio board? If so, was the issue resolved?

完成的

I’ve had a swollen battery on my MacBook and after the battery was changed with a new one, the speakers don’t seem to be working. Might it be a problem that the swollen battery has created? Maybe the tech that replaced it created the problem? What can be wrong and how can I find out what’s wrong?

Hi

Did you ever get to replacing the audio board? Further more, did that fix the problem? I’m having the same problem with my 12” Retina after replacing the keyboard.

Thanks.
