   4
   5This loads the driver for the Gravis Ultrasound family of sound cards.
   6
   7The gus module takes the following arguments
   8
   9io              I/O address of the Ultrasound card (eg. io=0x220)
  10irq             IRQ of the Sound Blaster card 
  11dma             DMA channel for the Sound Blaster
  12dma16           2nd DMA channel, only needed for full duplex operation
  13type            1 for PnP card
  14gus16           1 for using 16 bit sampling daughter board
  15no_wave_dma     Set to disable DMA usage for wavetable (see note)
  16db16            ???

  19no_wave_dma option
  20
  21This option defaults to a value of 0, which allows the Ultrasound wavetable
  22DSP to use DMA for playback and downloading samples. This is the same
  23as the old behaviour. If set to 1, no DMA is needed for downloading samples,
  24and allows owners of a GUS MAX to make use of simultaneous digital audio
  25(/dev/dsp), MIDI, and wavetable playback.

  27
  28If you have problems in recording with GUS MAX, you could try to use
  29just one 8 bit DMA channel. Recording will not work with one DMA
  30channel if it's a 16 bit one.
