[PROBLEM] alsa volume

[Tim Curtis]

If you are using the Subwoofer modes you need to install the Allo DSP firmware files.

See below 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

AFAIK the files are not part of Raspbian firmware cuz the license on the files restricts them from being redistributed,. Thus end-user is responsible for installing them.
