## Audio

The inbuilt audio used for the speakers and headset jack needs sof-firmware to be installed.

For headset microphones, set the volume for `PGA2.0 2 Master` under the sof-hda-dsp sound card to at least `32` in `alsamixer` and mute `Capture 1`. The mic mute LED will only follow the status of the internal mic.

## Keyboard backlight

Install dell-g15-controllerAUR for keyboard backlight control. Only static colors and morph effect is supported, and more complicated effects such as rainbow and breathing do not work yet.

## Game Shift Mode

First install acpi_call (or acpi_call-lts for LTS kernel, acpi_call-dkms for other kernels) and load the kernel module:

    # modprobe acpi_call

Turn on:

    # echo "\_SB.AMWW.WMAX 0 0x15 {1, 0xab, 0x00, 0x00}" > /proc/acpi/call
    # echo "\_SB.AMWW.WMAX 0 0x25 {1, 0x01, 0x00, 0x00}" > /proc/acpi/call

Turn off:

    # echo "\_SB.AMWW.WMAX 0 0x15 {1, 0xa0, 0x00, 0x00}" > /proc/acpi/call
    # echo "\_SB.AMWW.WMAX 0 0x25 {1, 0x00, 0x00, 0x00}" > /proc/acpi/call

Alternatively, the power mode and fan speed boost can be set using dell-g15-controllerAUR

## Accessibility

The appearance of the BIOS is pretty simple and not very colorful, so it might work well with OCR software. The use of a mouse is not required.

## Function keys

Key | Visible?1 | Marked?2 | Effect
--- | --- | --- | ---
`Fn+Esc` | No | Yes | Enables Fn lock
`Fn+F1` | Yes | Yes | Inputs `Super+k` (supposed to open bluetooth menu)
`Fn+F8` | Yes | Yes | Inputs `Super+p` (opens display settings)
`Fn+F10` | Yes | Yes | `XF86MonBrightnessDown`
`Fn+F11` | Yes | Yes | `XF86MonBrightnessUp`
`Fn+F12` | Yes | Yes | Inputs `Super+Ctrl+Zenkaku_Hankaku` (disabling the touchpad)

1. The key is visible to `xev` and similar tools.
2. The physical key has a symbol on it, which describes its function.
