Module supports autoprobe and multiple bus-master chips (max 8).
if you still encounter too fast playback, specify the clock
explicitly via the module option "ac97_clock=41194".
- The joystick and MPU-401 are supported only certain hardwares.
- MPU401 is experimental, It doesn't work perfectly.
+ Joystick/MIDI ports are not supported by this driver. If your
+ motherboard has these devices, use the ns558 or snd-mpu401
+ modules, respectively.
The ac97_quirk option is used to enable/override the workaround
for specific devices. Some hardware have swapped output pins
Note: One miXart8 board will be represented as 4 alsa cards.
See MIXART.txt for details.
+ When the driver is compiled as a module and the hotplug firmware
+ is supported, the firmware data is loaded via hotplug automatically.
+ Install the necessary firmware files in alsa-firmware package.
+ When no hotplug fw loader is available, you need to load the
+ firmware via mixartloader utility in alsa-tools package.

Module snd-mpu401
-----------------
buffer_top - specify buffer top address
use_cache - 0 or 1 (disabled by default)
vaio_hack - alias buffer_top=0x25a800
+ reset_workaround - enable AC97 RESET workaround for some laptops
Module supports autoprobe and multiple chips (max 8).
but some doesn't have ISA PnP. You'll need to speicfy isapnp=0
and proper hardware parameters in the case without ISA PnP.
+ Note: some laptops need a workaround for AC97 RESET. For the
+ known hardware like Dell Latitude LS and Sony PCG-F305, this
+ workaround is enabled automatically. For other laptops with a
+ hard freeze, you can try reset_workaround=1 option.
+
Note: This driver is really crappy. It's a porting from the
OSS driver, which is a result of black-magic reverse engineering.
The detection of codec will fail if the driver is loaded *after*
This module supports up to 8 cards, autoprobe and hotplugging.
+ Module snd-usb-usx2y

+ in alsa-tools and alsa-firmware packages.
+
Module snd-via82xx
------------------
Note: for the MPU401 on VIA823x, use snd-mpu401 driver
additonally. The mpu_port option is for VIA686 chips only.
