Hi y'all ,
The audio port on my MacBook Pro (13-inch, Mid 2009) 10.11.6 , is able to work as a line in but not as an output.
Theres is some audio but it is so low its negligible.
Ive checked the audio settings in system preferences and audio midi setup to no avail.
Ive only noticed this problem subsequent to using a USB adapter which works no problems as an output.
This option is no longer viable as I need the usb port for other purposes.
Ive also noticed in audio midi setup that the master lever is grayed out.
Thanks in advance.
