I am using Macbook, in ubuntu my external headphone does not work while my internal speaker works. Does anyone know how to fix this? Do I have to install a perfect driver?
One fix I found is that I can boot into MacOS then after next few days, headphone works in Ubuntu then.
These two 8-year posts did not work for me. No sound through headphones but works for internal speakers No sound through headphones while speakers work fine
