asfxload loads a soundfont onto ALSA's Emux wavetable. The old version sfxload works only with ALSA's OSS emulation. See the SoundfontHandling page for details of how to use soundfonts.

If you get the error "No Emux synth hwdep device is found" it is supposed to mean that your driver version is too old. I got this with kernel 2.6.2 and I am now upgrading to kernel 2.6.4, hoping that they upgraded the ALSA driver. I got the same error with 2.6.5-mm5 and ALSA built-in. I recompiled the kernel to include ALSA as modules and then I just had to modprobe emu10k1-synth to make everything work. -- tachyon


I'm using a 2.6.x kernel and the following line in /etc/modprobe.d/local loads the 8mbgmsfx.sf2 SoundFont automatically when the module is loaded:

install snd-emu10k1-synth /sbin/modprobe \
--ignore-install snd_emu10k1_synth;/usr/bin/asfxload 8mbgmsfx

Of cource you can load it manually instead:

/usr/bin/asfxload 8mbgmsfx

In Debian (Sarge), asfxload searches for sound fonts in:

  • /usr/share/sounds/sf2
  • /usr/share/sfbank
  • /usr/local/lib/sfbank
