It means that you have no Intel graphics on your machine, or i915 driver isn't used, or i915 driver isn't loaded properly before HD-audio. The remaining issue, the i915 error, is strange, though. See Documentation/sound/hd-audio/notes.rst 'Early Patching' section. Once when you figure out the setup, it can be put in 'patch' firmware file. BIOS often give the incorrect default pin configuration, and you may have to reprogram by yourself. Some of them might control the amplifier for the headphone and the speaker, according to the past experience with Apple devices.Īlso, you should check the detectable pins, e.g. Hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DATA 0x01 Hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_DIR 0x01 Hda-verb /dev/snd/hwC0D0 0x01 SET_GPIO_MASK 0x01 You can do both of them dynamically and via 'patch' firmware. The codec chip is unknown, so the driver applied the generic method, thus passing model option doesn't work at all since the model option is specific to the codec drivers.įor most of Macs, the required quirks are to reprogram the default pin configurations and to turn on the GPIO pins.
