Allo Piano 2.1 F/W crossover does not work.

[Takeshi Masumoto]

Hi,

 

I downloaded Piano 2.1 F/W from GitHub

and placed 44k 100Hz crossover .bin files into /lib/firmware/allo/piano/2.2 directory.

Then I rebooted Pi and measured white noise spectrum but crossover filters did not work.

 

Any suggestion will be appreciated.

 

Kind regards,

Takeshi

which OS  dietpi ? which version?   Normally on selecting the hardware the firmware files downloads and extracting in to /lib/firmware/

all files should be present in /lib/firmware/allo/ firmware folder.  Then only the mode selection will work.
