        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.

          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).

          Linux can often have problems allocating DMA buffers for ISA sound

          cards on machines with more than 16MB of RAM. This is because ISA

          DMA buffers must exist below the 16MB boundary and it is quite

          possible that a large enough free block in this region cannot be

          found after the machine has been running for a while. If you say Y

          here the DMA buffers (64Kb) will be allocated at boot time and kept

          until the shutdown. This option is only useful if you said Y to

          "OSS sound modules", above. If you said M to "OSS sound modules"

          then you can get the persistent DMA buffer functionality by passing

        ---help---

          Answer Y if you have an original Sound Blaster card made by Creative

          Labs or a 100% hardware compatible clone (like the Thunderboard or

          SM Games). For an unknown card you may answer Y if the card claims

          to be Sound Blaster-compatible.

          Please read the file .

          You should also say Y here for cards based on the Avance Logic

          ALS-007 and ALS-1X0 chips (read ) and

          for cards based on ESS chips (read

           and

          ). If you have an SB AWE 32 or SB AWE

          64, say Y here and also to "AWE32 synth" below and read

          . If you have an IBM Mwave

          card, say Y here and read .

          If you compile the driver into the kernel and don't want to use

          isapnp, you have to add "sb=,,," to the kernel

          command line.

          You can say M here to compile this driver as a module; the module is

          called sb.

config SOUND_YM3812

        depends on SOUND_OSS

        ---help---

          Answer Y if your card has a FM chip made by Yamaha (OPL2/OPL3/OPL4).

          Answering Y is usually a safe and recommended choice, however some

          cards may have software (TSR) FM emulation. Enabling FM support with

          these cards may cause trouble (I don't currently know of any such

          cards, however). Please read the file

           if your card has an OPL3 chip.

          If you compile the driver into the kernel, you have to add

          "opl3=" to the kernel command line.

          If unsure, say Y.

config SOUND_UART6850

          This option enables support for MIDI interfaces based on the 6850

          UART chip. This interface is rarely found on sound cards. It's safe

          to answer N to this question.

          If you compile the driver into the kernel, you have to add

          "uart6850=," to the kernel command line.

        depends on SOUND_OSS

        ---help---

          Answer Y if you have a Gallant's Audio Excel DSP 16 card. This

          driver supports Audio Excel DSP 16 but not the III nor PnP versions

          of this card.

          The Gallant's Audio Excel DSP 16 card can emulate either an SBPro or

          a Microsoft Sound System card, so you should have said Y to either

          "100% Sound Blaster compatibles (SB16/32/64, ESS, Jazz16) support"

          or "Microsoft Sound System support", above, and you need to answer

          the "MSS emulation" and "SBPro emulation" questions below

          accordingly. You should say Y to one and only one of these two

          questions.
