I own a working force and a force where the internal soundcard doesn't work anymore. On my “not well working force” i use a presonus USB soundcard. With this external soundcard, i have sound output only by using prime4.

To use prime 4, you have to change your productcode to JC11 when binding. (mount -o bind productcode “/sys/firmware/devicetree/base/inmusic,product-code”)

When running prime you'll see which file you can create for your assignments. Below is an example when i run prime 4 :

air.assignments.deviceadapter: Could not find file: "Akai_Pro_Force_Public_Assignments.qml"
air.assignments.deviceadapter: Could not find file: "Akai_Pro_Force_Public_Device.qml"
air.assignments.deviceadapter: Could not find file: "Akai_Pro_Force_Private_Assignments.qml"
air.assignments.deviceadapter: Could not find file: "Akai_Pro_Force_Private_Device.qml"
air.assignments.deviceadapter: Could not find file: "Akai_Pro_Force_MIDI_Port_Assignments.qml"
air.assignments.deviceadapter: Could not find file: "Akai_Pro_Force_MIDI_Port_Assignments.qml"
air.assignments.deviceadapter: Could not find file: "Akai_Pro_Force_MIDI_Port_Device.qml"
air.assignments.deviceadapter: Could not find file: "Akai_Pro_Force_MIDI_Port_Device.qml"
air.assignments.deviceadapter: Could not find file: "AudioBox_USB_96_MIDI_1_Assignments.qml"
air.assignments.deviceadapter: Could not find file: "AudioBox_USB_96_MIDI_1_Assignments.qml"
air.assignments.deviceadapter: Could not find file: "AudioBox_USB_96_MIDI_1_Device.qml"
air.assignments.deviceadapter: Could not find file: "AudioBox_USB_96_MIDI_1_Device.qml"

So all these qml files can be created.

Then you can use the following qml to use it on your force. (qml syntax has been taken from Prime Firmware)

Akai_Pro_Force_Public_Device Akai_Pro_Force_Public_Assignments

Akai_Pro_Force_Private_Device Akai_Pro_Force_Private_Assignments

I will explain a bit the syntax

_Private_ files are used for inputs / actions buttons .
