Step 5: Reset NVRAM/PRAM
Resetting the NVRAM (or PRAM) can sometimes resolve sound-related issues:
- Shut down your Mac.
- Turn it on and immediately press and hold Option, Command, P, and R keys.
- Keep holding them for about 20 seconds, during which your Mac will restart.
Advanced Solutions for Persistent Sound Issues
If you’ve tried all the basic techniques and still experience trouble with sound, consider some advanced solutions.
Check Audio MIDI Setup
- Open Audio MIDI Setup from Applications > Utilities.

Experiencing sound issues on your Mac can be frustrating and disruptive, especially when you’re in the middle of a crucial task. While the troubleshooting process may seem daunting, many simple solutions can resolve sound problems effectively.
By following the steps outlined in this guide, you will empower yourself to identify the root of the problem and implement effective solutions. Whether it requires a quick volume adjustment, checking settings, or performing advanced troubleshooting steps, you have the knowledge to rekindle the sound on your Mac.
For persistent issues, remember that seeking assistance from professionals is always a wise choice. Your Mac is a powerful tool, and with the right troubleshooting, you can ensure it continues to serve you without missing a beat!
What should I check first if my Mac’s sound isn’t working?
To troubleshoot sound issues on your Mac, start by checking the volume settings. Ensure that the volume is turned up and is not muted. You can do this by clicking on the sound icon in the menu bar or accessing the Sound settings in System Preferences. Additionally, make sure that your external speakers or headphones are properly connected and powered on.
If the volume levels are correct, check if the correct audio output device is selected. You can do this by going to System Preferences, selecting Sound, and then navigating to the Output tab. Here, you can see all available audio output devices. If your desired device is not active, click on it to make it the default output device.
How do I reset the NVRAM on my Mac to fix sound issues?
Resetting the NVRAM (non-volatile random-access memory) can sometimes resolve sound issues on your Mac. To do this, turn off your Mac completely. Then, turn it back on and immediately press and hold the Option, Command, P, and R keys together. Keep holding them for about 20 seconds, during which your Mac may restart.
After releasing the keys, your NVRAM will be reset, and you may need to go back into System Preferences to adjust certain settings like volume and display resolution. This step can help if there’s a miscommunication between the sound settings and output devices due to incorrect stored information.
Why does my Mac only play sound through headphones?
If your Mac plays sound only through headphones, it may be detecting a jack connection. This might happen if debris is lodged in the headphone port, making the Mac think headphones are still plugged in. Inspect the port and gently clean it with compressed air or a soft brush to remove any obstructions.
If cleaning does not resolve the issue, ensure that the sound output settings are correct. Go to System Preferences, select Sound, and check the Output tab to see if your internal speakers are listed as a possible output device. If you don’t see them listed, there could be a hardware issue that requires closer inspection by a technician.
What if my Mac’s sound suddenly stopped working during a video call?
When sound stops working during a video call, the first step is to check the audio settings within the application you’re using (such as Zoom, Skype, or Teams). Ensure that the application has the correct microphone and speaker selected. Sometimes, the application might default to a different output or input source, which can cause connectivity issues.
Next, verify any system-level audio settings by heading to System Preferences and checking both Sound preferences and the Audio/MIDI Setup application to confirm the right devices are active. Additionally, restarting the application or even your Mac can often resolve temporary glitches that affect sound during video calls.
How can I update my Mac to fix sound problems?
Keeping your MacOS up to date is essential for resolving various issues, including sound problems. To check for updates, click on the Apple menu in the top-left corner and select About This Mac. From there, click on Software Update, which will display any available updates and allow you to install them.
Updated software often includes bug fixes and performance improvements that can address sound-related issues. After installing any updates, be sure to restart your Mac to ensure all changes take effect properly. This simple step can often resolve underlying problems that were affecting the audio performance.
Are there any third-party applications I can use to diagnose sound issues?
Yes, there are several third-party applications that can help diagnose and troubleshoot sound issues on your Mac. Applications such as Sound Control or Boom 3D allow you to manage and enhance your sound settings more effectively. They also provide various diagnostic options that can help identify problems with audio output or input.
Additionally, some diagnostic utilities can test the audio hardware. Look for apps that specialize in hardware diagnostics to run comprehensive checks. Be sure to download such applications from reputable sources to ensure the security and integrity of your Mac.
Should I seek professional help if my sound issues persist?
If you’ve tried all troubleshooting steps and your Mac’s sound issues persist, it may be time to seek professional help. A licensed technician can diagnose more complex hardware problems, such as faulty speakers or internal sound cards. These issues often require specialized tools and knowledge to repair safely.
Before taking your Mac to an authorized service provider, ensure that you back up your data to avoid losing any important files during the repair process. Certified technicians can provide a comprehensive assessment and let you know the best course of action for your specific sound issues.
