5 | This loads the driver for the Gravis Ultrasound family of sound cards. | ||
6 | |||
7 | The gus module takes the following arguments | ||
8 | |||
9 | io I/O address of the Ultrasound card (eg. io=0x220) | ||
10 | irq IRQ of the Sound Blaster card | ||
11 | dma DMA channel for the Sound Blaster | ||
12 | dma16 2nd DMA channel, only needed for full duplex operation | ||
13 | type 1 for PnP card | ||
14 | gus16 1 for using 16 bit sampling daughter board | ||
15 | no_wave_dma Set to disable DMA usage for wavetable (see note) | ||
16 | db16 ??? | ||
17 | |||
18 | |||
19 | no_wave_dma option | ||
20 | |||
21 | This option defaults to a value of 0, which allows the Ultrasound wavetable | ||
22 | DSP to use DMA for for playback and downloading samples. This is the same | ||
23 | as the old behaviour. If set to 1, no DMA is needed for downloading samples, | ||
24 | and allows owners of a GUS MAX to make use of simultaneous digital audio | ||
25 | (/dev/dsp), MIDI, and wavetable playback. | ||
26 | |||
27 | |||
28 | If you have problems in recording with GUS MAX, you could try to use | ||
29 | just one 8 bit DMA channel. Recording will not work with one DMA | ||
30 | channel if it's a 16 bit one. | ||
