Static in External MIC #1

Hey there, great work on the EFI. I was wondering, were u able to get external input to work? When I try it, I only get static from mic plugged in through the jac, but the internal mix seems to be working fine.

I don’t have it right now, big update coming on the Weekend. Thanks though. I will try to reproduce the error when I’m home again.

Just in case, I was able to fix it by adding CodecCommander.kext and then using hda-verbs to set hda-verb 0x19 SET_PIN_WIDGET_CONTROL 0x24. Doing this fixes the external mic and it works perfectly. However, the issue is that you have to do it everytime you reboot, so I ended up using launchd for that. It still feels kinda hacky. Wondering if there's a better way to patch this in OC itself...
