[SOLVED] Possible fix for Allo Piano 2.1

[Tim Curtis]

This error suggests the fixed piano driver might not be exposing sone ALSA controls.

Code:

20241218 104130 worker: Allo Piano 2.1:   mode set to amixer: Unable to find simple control 'Dual Mode',0

Try this command in the home directory that prints the controls

Code:

./piano.sh

Then try the mixer command and see if the control named "Item0" exists and if so are the modes listed for example "Dual Mode", "Subwoofer mode" etc

Code:

mixer

This is the code block in /var/www/util/sysutil.sh that handles piano controls. The same commands are used in the home dir ./piano.sh script.

Code:
