After several years problem-free, now my Macbook has the Audio Echo problem. Macbook Pro 15" 2015 running High Sierra. Same problem as described above, echo in playback with Apple's DVD player, VLC and MPEG Streamclip, but not with Quicktime player. Does anyone know how to get rid of the echo?
Hi Donmar,
First, let's see if adjusting the sound outputs helps:
"On your Mac, choose Apple menu 
> System Preferences, click Sound, then click Output.
Select the device you want to use in the list of sound output devices.
All sound output devices available to your Mac are listed, including the computer’s internal speakers, devices plugged into your computer’s sound port (
), USB speakers, and AirPlay devices.
For any device plugged into the computer’s sound port, choose Headphones.
Do any of the following to adjust your sound output settings:
"
Change the sound output settings on Mac - Apple Support
Next, reset the NVRAM which "is a small amount of memory that your Mac uses to store and quickly access certain system settings such as sound volume."
Reset NVRAM on your Mac - Apple Support
Hope this helps.
Cheers.

Thank you but wouldn't having the same problem with apps from 3 different developers mean that the system on my Mac is not interfacing correctly with them?
Hey Donmar,
Potentially, but if other apps like Music, QuickTime, and others are working correctly, that means the Mac itself is working correctly. If an app from another developer is not working as expected on your Mac, it's likely going to be changes made on their end that would correct that. There also may be settings that have changed and need to be adjusted, which the developer of that app would know the most about. If you haven't worked with any of the devs on those apps thus far, that'd be a great next step just to get an idea of what suggestions they may have.
Be well.
Hi Neil22R, Thank you for taking the time to look for answers to this echo problem. I have tried everything that you have suggested. The echo problem persists. There's no echo on playback with Quicktime or the Elmedia Video player, but horrible echo-chamber-like echo on playback in VLC, 5K player and MPEG Streamclip. I've loved these apps for many years, always reliable, and as you probably already know, VLC is great because it plays everything. I've checked to be sure that I'm running the latest versions of all the apps, and have even tried deleting and re-installing VLC, 5K player and MPEG Streamclip, but I still get the horrible echo on playback. Any other suggestions are certainly welcome!
Hi there Donmar,
If you're only experiencing this audio echo in third-party apps on your Mac, try reaching out the the app developers directly to see if they can offer any additional guidance about how to adjust some of your audio settings.

Take care.
Will try, thanks!
