Chosen Solution
So, long story short, I recently bought an Early 2011 13" Macbook Pro. Everything’s working well, except for one thing, there is not any audio output or input at all. The single way I can output/input any sound is by connecting a BlueTooth device to my mac. And while that satisfies my needs, I’d like to try and resolve the audio issues with this device. This mac has the OpenCore Legacy Patcher applied to it, but I do not think that it affected the sound in any way, as it was absent even before applying that. Also, things I have tried to do till now are the following: re-plugging the left and right speakers on the motherboardplug and unplug an AUX cable in the jack 3.5mm port I have also run the apple hardware test tool and got the following error 4SNS/1/40000000: VDOR-18.108 What I’d like to know is wether it is an issue related to the main board, or a simple speakers’ and microphone replacement, will resolve the issue Below I have attached the diagnostic result, and what’s displayed in the output and input of sound settings.
You weren’t the very clear if the internal speakers work at all. So you get the startup chime? Setup a bootable external drive with macOS Sierra, then reboot an using the startup commands (option key) so you can use the external drive. Now using it are you able to use the internal speaker to work as well as a external headphone or speaker?
