This module supports multiple cards, autoprobe and ISA PnP.
+ Module snd-jazz16
+ -------------------
+
+ Module for Media Vision Jazz16 chipset. The chipset consists of 3 chips:
+ MVD1216 + MVA416 + MVA514.
+
+ port - port # for SB DSP chip (0x210,0x220,0x230,0x240,0x250,0x260)
+ irq - IRQ # for SB DSP chip (3,5,7,9,10,15)
+ dma8 - DMA # for SB DSP chip (1,3)
+ dma16 - DMA # for SB DSP chip (5,7)
+ mpu_port - MPU-401 port # (0x300,0x310,0x320,0x330)
+ mpu_irq - MPU-401 irq # (2,3,5,7)
+
+ This module supports multiple cards.
+
Module snd-korg1212
-------------------
The power-management is supported.
+ Module snd-ua101
+ ----------------
+
+ Module for the Edirol UA-101 audio/MIDI interface.
+
+ This module supports multiple devices, autoprobe and hotplugging.
