Hi there,
I noted that on the uConsole there is a button above the “6” key which has an orange “x” symbol as well as a volume icon with an up and down arrow. When pushing this button normally (without the 'fn key) I noted that it lowers the volume. If I use the ‘fn’ key, it mutes the audio. However, is there a way to raise the volume using this key? The up arrow makes me think there must be a way to do this, but maybe not?
try
fn + shift + volume key
Didn’t work on A-06 uConsole using system pre-flashed on TF card. Do I need upgrade system image?
it is not related to os image, it is related to keyboard firmware
if fn+shift+volume key did not work, maybe need to upgrade keyboard firmware
I can confirm that it is firmware related. Once I updated my firmware, pushing the button reduces the volume while Fn+button increases the volume.
fixed after updating keyboard firmware.
but Fn+Volume is volume up, not mute, which a bit of odd…
Do uConsole’s keyboard still using the same code of devterm? I may build a new firmware to accommodate my personal usage habits.
not the same
here is the code address
I noted this strange behavior as well. However, I’d rather have volume down and up over volume down and mute 
Hi, I came across the same issue!
My module is R-01.
When updating this flash, it says
unknow architecture,exiting...
Now, my device stays muted, I tried the alsamixer but failed, help
#!/bin/bash
#set -e
architecture="unknow"
case $(uname -m) in
x86_64) architecture="amd64" ;;
armv7l) dpkg --print-architecture | grep -q "arm64" && architecture="aarch64" || architecture="armhf" ;;
arm) dpkg --print-architecture | grep -q "arm64" && architecture="aarch64" || architecture="armhf" ;;
aarch64) architecture="aarch64";;
esac
if [ $architecture = "unknow" ]; then
echo "unknow architecture,exiting..."
exit
fi
here is the flashing script code, as we can see ,it just check the architecture of device, nothing more
so the Mute problem is not related
Thanks, it seems that uconsole_keyboard_flash.tar.gz doesn’t apply to RISC-V archtecture.
One can unmute your device via alsamixergui
Now
re-download the uconsole_keyboard_flash.tar.gz
md5sum is
0ed78754e3b998d3e023b9568758a22f
now it has applied to RISC-V archtecture
welcome to have a try
I took the riscv64 bin files from Keyboard Update for R01
@comradecactus
OK, I tried modify keyboard’s firmware to make Shift+Volume=Volume Up and Fn+Volume=Mute.
Code seems working, except Volume up is not. I can see it’s sending keycode using showkey command.
@guu The volume up keycode is 115, volume down is 114, mute is 113, is this correct?
try with a normal keyboard to detect the right keycode ,with command like xev
but I’ve looked at the code
seems that ,I use enum to define
volume up,down, mute
enum SKEYS {
_SELECT_KEY =0xe8, //Joystick.button(n)
_START_KEY, //Joystick.button(n)
_JOYSTICK_UP, //B1 //Joystick.Y()
_JOYSTICK_DOWN, //Joystick.Y()
_JOYSTICK_LEFT, //Joystick.X()
_JOYSTICK_RIGHT, //Joystick.X()

_TRACKBALL_BTN,
_FN_LOCK_KEYBOARD,
_FN_LIGHT_KEYBOARD,
_FN_SHIFT //FN+SHIFT,ready for more function key
};
I found the problem… keycode is correct, but any volume key cannot be pressed with shift!
To deal with it, I tried release shift key before sending press volume up, and it worked. 
Here is diff for my use case (volume key=volume down, Shift key+volume key=volume up, Fn key+volume key=mute)
I will make a fork of uconsole’s repo and make all these changes in it. If you like to merge it into official repo, I can make a PR.

cool
give me the PR
I want to try it out
