+ Module snd-azt1605
+ ------------------
+
+ Module for Aztech Sound Galaxy soundcards based on the Aztech AZT1605
+ chipset.
+
+ port - port # for BASE (0x220,0x240,0x260,0x280)
+ wss_port - port # for WSS (0x530,0x604,0xe80,0xf40)
+ irq - IRQ # for WSS (7,9,10,11)
+ dma1 - DMA # for WSS playback (0,1,3)
+ dma2 - DMA # for WSS capture (0,1), -1 = disabled (default)
+ mpu_port - port # for MPU-401 UART (0x300,0x330), -1 = disabled (default)
+ mpu_irq - IRQ # for MPU-401 UART (3,5,7,9), -1 = disabled (default)
+ fm_port - port # for OPL3 (0x388), -1 = disabled (default)
+
+ This module supports multiple cards. It does not support autoprobe: port,
+ wss_port, irq and dma1 have to be specified. The other values are
+ optional.
+
+ "port" needs to match the BASE ADDRESS jumper on the card (0x220 or 0x240)
+ or the value stored in the card's EEPROM for cards that have an EEPROM and
+ their "CONFIG MODE" jumper set to "EEPROM SETTING". The other values can
+ be choosen freely from the options enumerated above.
+
+ If dma2 is specified and different from dma1, the card will operate in
+ full-duplex mode. When dma1=3, only dma2=0 is valid and the only way to
+ enable capture since only channels 0 and 1 are available for capture.
+
+ Generic settings are "port=0x220 wss_port=0x530 irq=10 dma1=1 dma2=0
+ mpu_port=0x330 mpu_irq=9 fm_port=0x388".
+
+ Whatever IRQ and DMA channels you pick, be sure to reserve them for
+ legacy ISA in your BIOS.

Module snd-sscape
-----------------
To compile this driver as a module, choose M here: the module
will be called snd-dummy.
+config SND_ALOOP
+ tristate "Generic loopback driver (PCM)"
+ select SND_PCM
+ help
+ Say 'Y' or 'M' to include support for the PCM loopback device.
+ This module returns played samples back to the user space using
+ the standard ALSA PCM device. The devices are routed 0->1 and
+ 1->0, where first number is the playback PCM device and second
+ number is the capture device. Module creates two PCM devices and
+ configured number of substreams (see the pcm_substreams module
+ parameter).
+
+ The looback device allow time sychronization with an external
+ timing source using the time shift universal control (+-20%
+ of system time).
+
+ To compile this driver as a module, choose M here: the module
+ will be called snd-aloop.
