| 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 |
| Paolo Ornati | 670e9f3 | 2006-10-03 22:57:56 +0200 | [diff] [blame] | 22 | DSP to use DMA for playback and downloading samples. This is the same |
| Linus Torvalds | 1da177e | 2005-04-16 15:20:36 -0700 | [diff] [blame] | 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. |
