the sound on my macbook is distorted, how do I check that the soundcard is working ok please?
When I listen to a podcast or music on my macbook, the sound is very muffled/distorted and I can't hear it clearly at all. I've gone through the hardware fault detection process and it's not showing an issue. Can anyone help please?
I'm using Mojave 10.14.6 as I don't think I have enough memory to upgrade to the latest software. Not sure if that would make a difference...
Thanks so much for any advice.
MacBook Pro 15″, macOS 10.14
