Safari audio is suddenly tinny & distorted

[Namingishard]

All audio coming from Safari and Safari only is very tinny, echoey and distorted.

I've look this up and all i can find are people saying they have this issue when they speed up the playback on youtube. My playback speed is set to normal. It doesn't just happen on youtube either, its any audio played through Safari, other browsers, computer audio, iTunes are all fine. Its just Safari.

It started out of no where last night. Resetting my PRAM did nothing, resetting the computer, updating all did nothing to help the issue. Does anyone know whats causing this or how to fix it?

Macbook pro 2011

High Sierra

Safari Version 12.1.2 (13607.3.10)

If videos are playing fast it is easy fix just open /Applications/Utilities/Activity.app and find the running app for CoreAudio service and force quit it.

This video will explain it better then me:

In case my original post is confusing no im not having an issue with videos playing back fast. All audio coming from Safari only is echoey and distorted. Audio from soundcloud, youtube, facebook etc

Just now listened to several music videos, viewed a couple instructional videos on YouTube, and audio was perfect; no problems. This is on a 2013 15" rMBP running the latest Mojave and Safari. I don't think the problem is with Safari.

yeah, i don't know what you mean. Obviously its not all Safari browsers, its my specific Safari browser. But it is a problem within Safari and Safari only.

I mean it may be something in your system or preferences that is causing the problem. 4other different Macs here all have good audio function with Safari

Something you can try: go to the sound settings>input and make sure the input is set to 'internal microphone' built in.
I've had exactly that issue with some headphones which have a mic and change that setting giving a sound like it's playing in tin cup or something so it could be that.

Do you have any browser extensions installed in Safari? If so, disable all of them, even the ones you think can't possibly affect audio.


Do you have another user account you can login to? Not just a browser profile, but an actual Mac user account, in System Preferences > Users and Groups. If not, make one. Then login to it, and launch Safari. Does it have the problem? If so, then it's probably being caused by a system component of some kind, or a browser extension you've made available system-wide. If Safari in the new user account works fine, then the problem is definitely with something specific to your original user account, and not something system-wide.
