Allo Piano 2.1 problem in 2.1 mode

[Tim Curtis]

The symptoms suggest the Allo DSP files which are necessary for the Subwoofer modes are not installed.

These files cannot be bundled in a Linux distribution because of license restrictions. They have to be downloaded and installed by end user.

Below is the procedure from moOde Build Recipe

Code:

////////////////////////////////////////////////////////////////

// COMPONENT 9 - Allo Piano 2.1 Firmware

cd ~
wget https://github.com/allocom/piano-firmware/archive/master.zip
sudo unzip master.zip
sudo rm ./master.zip
sudo cp -r ./piano-firmware-master/lib/firmware/allo /lib/firmware
sudo rm -rf ./piano-firmware-master

if I set the volume to 0, I hear the sw anyway. 
what am I doing wrong 

[Tim Curtis]

Try setting MPD volume control to Hardware.

[alexlbz]

the mpd volume controlled by hardware. the problem still there!

[Tim Curtis]

After setting volume to 0 post the output of the command below

Code:

./piano.sh

[alexlbz]

don't work 

no matter what i do .... i turn the player volume to 0 ( left and right channel are still ) and the sw always go on diligently ... bam bam bam

normally, all channels should be silent if i turn the player volume to 0!?
