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.

Yamaha YMF-724/740/744/754 (DS-1) devices

This page describes how to enable support for audio devices based on Yamaha YMF chipsets on Debian systems.

snd-ymfpci is a Linux kernel module supporting Yamaha YMF-724/740/744/754 PCI audio controllers. It is an ALSA driver provided in Linux 2.6 mainline kernels. The driver is also available through 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.


You are required to supply three firmware files for device use, which can be acquired from the ALSA project.

  1. Install the alsa-base, alsa-utils packages 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 ymfpci && make
  4. Install the firmware to your system:

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

    # modprobe -r snd-ymfpci ; modprobe snd-ymfpci
  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(1) to unmute channels and raise the volume levels.

  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

The page HowToIdentifyADevice/PCI explains how to identify a PCI device.

The following list is based on the alias fields of modinfo snd-ymfpci in Debian 3.2.0 (3.2.51-1) kernel images.
