Then, I saw a suggestion to use the audio balance slider to find out which speaker was busted (if it was only one). After I copied and pasted those three words into a new Terminal window, hit Return and typed in my password, the sound quality remained fuzzy.Īnd while those solutions didn't work, I provide them here in case any of them work for someone else. The final fix I found online suggested opening Terminal to run the command sudo killall coreaudiod, to discover if the issue was rooted in Apple's Core Audio, a low-level API that manages sound. Unfortunately, videos and songs sounded equally bad on the guest account. If Guest isn't available, open System Preferences, click Users, click Login Options and enable guest login.
To do that, you restart your computer and select Guest when logging in. The next suggestion had me sign on as a Guest user, to see if the issue was limited to a setting for the account. The first trick I found was to reset the NVRAM and PRAM, which you do by booting the computer while holding down Command, Option, P and R, until you hear two chimes.īut as those two chimes rang, each with the same distortion I'd heard before, I knew that wasn't the right trick.
