# Regarding kernel modules, darp6 needs system76-acpi-dkms, not system76-dkms:

# [1] https://github.com/pop-os/system76-dkms/issues/39
|
|
# jackpot51> system76-acpi-dkms is the correct driver to use on the darp6
|
|
#
|
|
# system76-io-dkms also appears to be loaded on darp6 with Pop!_OS, and
|
|
# system76-dkms does not, and in fact refuses to load.

The vendor ID of the sound card PCI device, for applying the headset fixup.
|
|
This should be set to the value of the following file on your Darter Pro:

/sys/class/sound/hwC0D0/vendor_id
|

If this option has the default null value, then the headset fixup will

not be applied.

The subsystem ID of the sound card PCI device, for applying the headset fixup.
|
|
This should be set to the value of the following file on your Darter Pro:
|
|
/sys/class/sound/hwC0D0/subsystem_id
|
|
If this option has the default null value, then the headset fixup will

For full Darter Pro support, set the options:
|
|
- hardware.system76.darp76.soundVendorId
|
|
- hardware.system76.darp76.soundSubsystemId
|
|
You can copy these values directly from:
|
|
- /sys/class/sound/hwC0D0/vendor_id
|
|
- /sys/class/sound/hwC0D0/subsystem_id
|
|
The headset audio fixup will not be applied without these values.
|
|
Set these options to null to silence this warning.
