When I try to adjust the volume, the icon is grayed out. When I reboot, there is no chime. And when I go into the sound settings, it doesn’t show an output. I have tried resetting the PRAM and the SMC. Do I have to replace the speakers? Any help would be appreciated.
does it work with headphones connected? is there a red light on in the headphone port? if so, its stuck in digital audio mode… otherwise, its likely to be either a faulty with the logic board, or a possible software glitch. naturally its easier to start with the software, so try doing a clean install (on an external drive if you don’t want to do one on your internal drive)
Plug your headphones back in. Play a bit of sound through them (e.g., a song), then stop the sound. Make sure Preferences is quit. Launch Preferences and open the Sound pane. While the Sound pane is open and set to Headphones, pull out the headphone plug from the jack. It will reset itself to “Internal Speakers” and you are good to go… this should work.as it worked for me
Try manually deleting the following folder and doing a reboot.: Library->Preferences: Audio If this Answer is helpful please remember to return and mark it Accepted.
You will need to use the device and possibly the jack you last used on the device output last used. In my case I used a Samsung Soundbar for a television set (testing it). Below are the steps that worked for me. Step 1. Plug in device and jack last used that caused the issue. Step 2. Play iTunes through the jack and device. Step 3. Pause the sound. Step 4. Launch System Preferences (make sure it was closed prior to step 1). Step 5. Go to output tab. Step 6a. Unplug the Jack and it will reset to internal speakers. (if not go to Step 6b) Step 6b. While remaining on Output tab of system preferences, continue to plug and unplug the jack connected to the output device and it should reset itself after several attempts. You can always see the red indicator light as you insert in the jack and if the light is no longer present, you are successful and the output field will display the text Internal Speakers. Good luck!
1.spotlight 2.lauch activity monitor 3.in the search, type coreaudio 4.kill this process Note:in all this, ensure you have an earpiece plugged in. This fixes the issue 99% of the time. If all fails, restart.
go to system preferences - audio - internal speakers and tick that box mine did this today and this fixed it
In the old days, deleting plist files often solved many issues. This is what I did after my Sound panel preferences were dimmed and no longer connecting to external Wi-Fi and Macmini speakers. Find the sounds.plist file and delete it, then reboot your main computer.
My case was the HDMI. Just unplugged, sound came back to speaker (When HDMI connected, mac switches audio to it)
