RME Hammerfall DSP

PaulDavis is the maintainer of the code for this card.

modules.conf

PaulDavis has supplied his audio section from his modules.conf file.

This is the audio-related section. The only option you need worry about is the snd-enable option to \</code>snd-hammerfall-mem.o\</code>, and even that is optional because by default the module will just allocate memory for every Hammerfall or Hammerfall DSP device that it finds.

# Here, we leave the CS4232 
#MIDI interface undefined, since it uses a
# physical interface that is only accessible from within the case of
# the machine and I'm not interested in using it. To use it, set:

Trevor added: I gave up on ALSA for my Libretto 70, went back to OSS. Using the Gentoo distribution of ALSA. The midi_port definition is where it hangs A true bug, but the kernel OSS module opl3sa2 works fine. -- trevor @ dontspam me @ trevormarshall dotty com
