config SOUND_BCM_CS4297A
	tristate "Crystal Sound CS4297a (for Swarm)"
	depends on SOUND_PRIME && SIBYTE_SWARM
	help
	  The BCM91250A has a Crystal CS4297a on synchronous serial
	  port B (in addition to the DB-9 serial port).  Say Y or M
	  here to enable the sound chip instead of the UART.  Also
	  note that CONFIG_KGDB should not be enabled at the same
	  time, since it also attempts to use this UART port.

config SOUND_VWSND
	tristate "SGI Visual Workstation Sound"
	depends on SOUND_PRIME && X86_VISWS
	help
	  Say Y or M if you have an SGI Visual Workstation and you want to be
	  able to use its on-board audio.  Read
	  <file:Documentation/sound/oss/vwsnd> for more info on this driver's
	  capabilities.

config SOUND_HAL2
	tristate "SGI HAL2 sound (EXPERIMENTAL)"
	depends on SOUND_PRIME && SGI_IP22 && EXPERIMENTAL
	help
	  Say Y or M if you have an SGI Indy or Indigo2 system and want to be able to
	  use its on-board A2 audio system.

	select SND_AC97_CODEC
	depends on SOUND_PRIME && (SOC_AU1550 || SOC_AU1200)

config SOUND_TRIDENT
	tristate "Trident 4DWave DX/NX, SiS 7018 or ALi 5451 PCI Audio Core"
	depends on SOUND_PRIME && PCI
	---help---
	  Say Y or M if you have a PCI sound card utilizing the Trident
	  4DWave-DX/NX chipset or your mother board chipset has SiS 7018
	  or ALi 5451 built-in. The SiS 7018 PCI Audio Core is embedded
	  in SiS960 Super South Bridge and SiS540/630 Single Chipset.
	  The ALi 5451 PCI Audio Core is embedded in ALi M1535, M1535D,
	  M1535+ or M1535D+ South Bridge.

	  Use lspci -n to find out if your sound card or chipset uses
	  Trident 4DWave or SiS 7018. PCI ID 1023:2000 or 1023:2001 stands
	  for Trident 4Dwave. PCI ID 1039:7018 stands for SiS7018. PCI ID
	  10B9:5451 stands for ALi5451.

	  This driver supports S/PDIF in/out (record/playback) for ALi 5451
	  embedded in ALi M1535+ and M1535D+. Note that they aren't all
	  enabled by default; you can enable them by saying Y to "/proc file
	  system support" and "Sysctl support", and after the /proc file
	  system has been mounted, executing the command

		command			what is enabled

	  echo 0>/proc/ALi5451	pcm out is also set to S/PDIF out. (Default).

	  echo 1>/proc/ALi5451	use S/PDIF out to output pcm data.

	  echo 2>/proc/ALi5451	use S/PDIF out to output non-pcm data.
	  (AC3...).

	  echo 3>/proc/ALi5451	record from Ac97 in(MIC, Line in...).
	  (Default).

	  echo 4>/proc/ALi5451	no matter Ac97 settings, record from S/PDIF
	  in.


	  This driver differs slightly from OSS/Free, so PLEASE READ the
	  comments at the top of <file:sound/oss/trident.c>.

config SOUND_MSNDCLAS
	tristate "Support for Turtle Beach MultiSound Classic, Tahiti, Monterey"
	depends on SOUND_PRIME && (m || !STANDALONE)
	help
	  Say M here if you have a Turtle Beach MultiSound Classic, Tahiti or
	  Monterey (not for the Pinnacle or Fiji).

	  See <file:Documentation/sound/oss/MultiSound> for important information
	  about this driver.  Note that it has been discontinued, but the
	  Voyetra Turtle Beach knowledge base entry for it is still available

	  The Pinnacle and Fiji card resources can be configured either with

	  use of the IDE and joystick peripherals on the card as well; these
	  do not show up when the card is in PnP mode. Specifying zero for any
	  resource of a device will disable the device. If you are running the

	  configure the card's resources.
