macbook pro os x 9 headphones not working

Well, I guess I will try the latest updates, and if that doesn't work, kiss the headphone jack good bye. But I have a black plastic protective cover on it. It wasnt dropped, just bumped the side of it agains a stainless steel shelf. Hmmm, I did bump the macbook pro pretty good the other day when I was designing some duct work in a room. The red laser light has now finally stopped turning on randomly and stays off.My headphones still dont work after holding the ctrl + shift and power button trick.Īny other ideas? It used to work, then all of a sudden, I went to use it tonight, and the internal speakers stay on, but the headphones never kick in.Note: In my case 'hda intell Haswell' hardware card 0: does have all 5 of the boxes checked (4) Uncheck the lower left check box to 'iec958 default pcm' (3) Uncheck the lower left check box to 'iec958' (2) Find and select the hardware device that controls the digital audio, and in my case this was the: cirrus logic (1:) card (1) Run Qas Mixer, and on the right side of the window, look for 'Mixer device' and select 'hw - card' and look through the 0: 1: and 2:, etc, options, for the different audio devices for the sound card and usb audio devices. In Ubuntu 20.04 LTS linux, I installed Qas mixer: sudo apt-get update

It involves turning off the digital portion of the hw card (cirrus logic device in this case), and not changing the other hardware card or usb sound settings. Here are more details, where this solution that has worked permanently for weeks and is still working. I confirmed that sakell's solution above works on ubuntu 20.04 LTS in a macbook pro a1502 (year 2014), where the solution of installing QasMixer is in the youtube video link given by sakell: įor a macbook pro, a1502 (2014), I tried many solutions including directly using alsa mixer, etc, and editing files and directory settings, but none of them worked to turn off the red light that would turn on at the headphone port for the digital optical audio output, when there was no digital audio used, and when the ubuntu sound settings were all set to analog output speakers.
