Comment: Install to /lib/firmware: Debian's udev firmware loading agent (firmware.agent) was replaced by systemd's upstream builtin (50-firmware.rules) post-Wheezy, which does not search /usr; update devices.

ESS Maestro3/Allegro devices

This page describes how to enable support for sound devices based on the Maestro3/Allegro chipset on Debian systems.

snd-maestro3 is a Linux kernel module supporting ESS Technology's Maestro3/Allegro PCI audio controller. It is an ALSA driver provided in Linux 2.6 mainline kernels. The driver is also available via the alsa-source package.

In linux-2.6 2.6.23-1, the binary-only firmware in this driver was removed (see the package changelog), due to discovered licensing issues. This was also removed from the alsa-source package to resolve bug 483918.

Installation

You are required to supply two firmware files in order to use this device, which can be acquired from the ALSA project.

  1. Install the alsa-base, alsa-utils and build-essential packages:

    $ su
    # aptitude update
    # aptitude install alsa-base alsa-utils build-essential
    # exit
  2. Acquire an alsa-firmware tarball (> 1.0.13) from the ALSA project's server, for example:

    $ wget http://mirrors.zerg.biz/alsa/firmware/alsa-firmware-1.0.25.tar.bz2
  3. Extract the tarball and create firmware from binary DSP code:

    $ tar xvf alsa-firmware-1.0.25.tar.bz2
    $ cd alsa-firmware-1.0.25
    $ ./configure
    $ cd maestro3 && make
  4. Install the firmware to your system:

    $ su
    # mkdir /lib/firmware/ess
    # cp *fw /lib/firmware/ess
  5. Reload the snd-maestro3 module:

    # modprobe -r snd-maestro3 ; modprobe snd-maestro3
  6. If not already performed, add your user account to the audio group, then log out and log back into your system:

    # adduser yourusername audio
    # exit
    $ exit
  7. Run alsamixer, unmute the channels by using the M key and raise sound levels by using the UP arrow key:

    $ alsamixer
  8. Test the sound device, for example:

    $ aplay /usr/share/sounds/alsa/Noise.wav
    $ speaker-test -t sine -f 440 -c 2
    $ speaker-test -t wav -c 2

Supported Devices
