external speakers to work, I need to use HDA Analyser to change the
settings otherwise things remain stuck on the internal speaker. I did not

microphone - I can hear a recording, but the level is too low for practical
use.

mac mini box does not produce an audible recording :P

Advanced information - PCI Vendor/Device/Subsystem ID's
!!-------------------------------------------------------

00:1b.0 0403: 8086:1c20 (rev 05)
Subsystem: 8086:7270

your macmini pci subsystem is also 8086:7270 which is same as imac27

the pin default of your macmini (init_pin_config) is replaced by the pin
config of model imac27 (driver_pin_config)

Codec: Cirrus Logic CS4206
Address: 0 AFG Function Id: 0x1 (unsol 0)
Vendor Id: 0x10134206
Subsystem Id: 0x106b2100

is the subsystem id in codec unique ?
