8. How to use K9 AKM as a USB DAC function to connect to a computer?
【Windows computer】
1. Install the FiiO DAC universal driver on the computer: Click
Notice:
a. This version of the driver can only be used in Win10 and Win11 systems. Win7 and Win8 are not applicable.
b. If you have already installed other versions of the driver, please disconnect all FiiO devices from the computer when installing the 5.58 driver (otherwise it may cause a file missing prompt after the 5.50 version is installed).
2. K9 AKM input setting: K9 AKM [INPUT] switches to USB gear.
3. K9 AKM output setting: switch to the corresponding output port according to the interface used, switch to [PO] on the front panel, switch to [PRE] or [LO] on the rear panel.
4. Connect the computer and K9 AKM through a square USB data cable, set the audio output of the computer system and the audio output of the playback software to K9 AKM and then use it.

【MAC computer】
MAC computers do not need to install drivers, just select and set the corresponding sound output device.
It is recommended to adjust the system volume to the maximum, and adjust the output volume of the machine by adjusting the potentiometer.

【Linux computer】
The Linux system is driver-free. In theory, it can be used directly by connecting it. However, due to the large number of versions, there is no guarantee that all systems can be adapted. If it is connected, it is recommended to use other data cables or USB ports to check. If it is not recognized, it should be is not supported.
Does K9 AKM support driver-free function?
Supported, you can switch to USB 1.0 driver-free mode in Fiio Control App, and can decode PS5 and other devices
Why can’t K9 be recognized and used (USB) on win7 or win8 system computers?
The provider that provides us with USB DAC driver solutions has made it clear that it is no longer compatible with win7 and win8 systems in 2021, and only retains support for win10 and win11 systems.
In order to solve the problem of errors when users mistakenly use XMOS firmware to upgrade, we have decided after research to use a separate PID for each model of subsequent new products as a basis for upgrade judgment. It turns out that FiiO's old models share the same PID. K9 AKM uses a new PID, which cannot be recognized by versions 5.30 and below. It needs to be updated to version 5.50 or above.
Therefore, driver version 5.50 and above must be installed to use K9 AKM, and K9 AKM is not compatible with win7 and win8 systems.
How can I make K9 AKM recognized by the computer on win7 system?
There are currently two options:
Option 1: FiiO provides the firmware to users. Users can find a computer with win10 or win11 system and flash the K9 AKM to the PID of the old model.
Option 2: FiiO provides firmware and operation tutorials to users. Users follow the instructions on their win7 computers to crack the driver, so that after win7 recognizes the K9 AKM, the PID of the K9 AKM is upgraded to the old version.
