uConsole: Volume / Mute button?

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?


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 :smiley:

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 :smiley:


#set -e

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";;

if [ $architecture = "unknow" ]; then
        echo "unknow architecture,exiting..."

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 :smiley:

re-download the uconsole_keyboard_flash.tar.gz

md5sum is


now it has applied to RISC-V archtecture

welcome to have a try

I took the riscv64 bin files from Keyboard Update for R01
