[SOLVED] Possible fix for Allo Piano 2.1

[Sunfish]

output of ./piano.sh

Code:

amixer: Unable to find simple control 'Dual Mode',0

amixer: Unable to find simple control 'Subwoofer mode',0

amixer: Unable to find simple control 'Subwoofer',0

amixer: Unable to find simple control 'Lowpass',0

amixer: Unable to find simple control 'Master',0

Dual mode:
Subw mode:
Sub xover:
Sub level:
Mstr levl:

The command alsamixer gives: "This sound device does not have any controls. "

Bummer.
Looks like I have to connect to the RPiOS developers?

Still the sound from the system is really good. Looks (sounds) like the system is running in stereo modus (2.0).
