Q: Mid 2011 iMac 27 inch (Digital Output not working)
Hello,
I have a iMac mid 2011 27 inch, problem is the sound is greyed out and cannot be controlled or anything. Simply not working. However it works in windows and works when plugged in with a USB headset. People recommended resetting/killing coreaudiod but coreaudiod process does not show on activity monitor and when reset through terminal nothing happens. I have recently replaced the graphics card aswell due to graphic cards issues if that helps with anything. I have went to the console log and this is the errors that came up that is related to coreaudiod this is the log file.

I have tried absolutely everything. It is currently running El captain.
What I have tried so far:
Resetting coreaudiod
Resetting SMC
Resetting PRAM
Cleaned with toothpick and air compressed to make sure not dirt or anything is stuck in there.
No red line shows in audio jack
Reinstalling el captain operating system
Checked if muted buttons are unchecked and indeed they were
Repair disk and file permissions
I am super confused now and have no idea what more can be done. I am trying to avoid putting in a new logic board.
If anybody can help or has encountered this problem i would highly appreciate it if you could help thank you so much and have a good one.
iMac, iOS 10, null
