Earphone audio not working if system not start with earphone plugged

[Zardinality]

If the system does not start with earphones plugged, the audio setting will only show the speaker as output, in which case the speaker works as normal. If the earphone is plugged before the system starts everything is fine(though the lowest but not the mute level of the volume is considerably loud to me, I would not consider it as an issue).

That might be a VoodooHDA problem, I suggest you use AppleALC. To use AppleALC, enable kernel block "fix AppleALC" in my newly efi and use ALCPlugFix to fix ExtMic problem.

It is alright for me to boot without pluging in the earphone while using VoodooHDA, and I think ALCPlugFix maybe the key solution.

@EchoEsprit Thanks for the advice. I used the newest EFI now and it should be using AppleALC. This problem still replicates, that's a weird one. Any other idea why it is that way?

Confirmed it is because I installed a sunflower.kext in the previous version system. Now everything is normal, I hereby close this issue.
