MacBook – way to set Sound Balance permanently for MacBook

audiomacbook proterminal

My left speaker of Macbook pro is producing a bit muffled sound. So I have turned the Sound Balance setting in System Preferences towards midway through right speaker, and it's no longer noticeable.

However, this goes off every time system restarts and I've to move the slider to right again. Is there a way to set this permanently (via terminal maybe?)

Best Answer

I once had the same problem and resolved it.

Issue the following commands.

$ mv /Library/Preferences/com.apple.soundpref.plist /Library/Preferences/com.apple.soundpref.plist.backup

$ mv /Library/Preferences/Audio/com.apple.audio.DeviceSettings.plist /Library/Preferences/Audio/com.apple.audio.DeviceSettings.plist.backup

$ mv /Library/Preferences/Audio/com.apple.audio.SystemSettings.plist /Library/Preferences/Audio/com.apple.audio.SystemSettings.plist.backup

Then select whatever preference of sound settings you want and restart the MacBook.
