  Module snd-nm256
  ----------------

    Module for NeoMagic NM256AV/ZX chips

    playback_bufsize - max playback frame size in kB (4-128kB)
    capture_bufsize  - max capture frame size in kB (4-128kB)
    force_ac97       - 0 or 1 (disabled by default)
    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
    reset_workaround2 - enable extended AC97 RESET workaround for some
		      other laptops

    This module supports one chip and autoprobe.

    The power-management is supported.

    Note: on some notebooks the buffer address cannot be detected
    automatically, or causes hang-up during initialization.
    In such a case, specify the buffer top address explicitly via
    the buffer_top option.
    For example,
      Sony F250: buffer_top=0x25a800
      Sony F270: buffer_top=0x272800
    The driver supports only ac97 codec.  It's possible to force
    to initialize/use ac97 although it's not detected.  In such a
    case, use force_ac97=1 option - but *NO* guarantee whether it
    works!

    Note: The NM256 chip can be linked internally with non-AC97
    codecs.  This driver supports only the AC97 codec, and won't work
    with machines with other (most likely CS423x or OPL3SAx) chips,
    even though the device is detected in lspci.  In such a case, try
    other drivers, e.g. snd-cs4232 or snd-opl3sa2.  Some has ISA-PnP
    but some doesn't have ISA PnP.  You'll need to specify 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: Dell Latitude CSx laptops have another problem regarding
    AC97 RESET.  On these laptops, reset_workaround2 option is
    turned on as default.  This option is worth to try if the
    previous reset_workaround option doesn't help.

    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*
    X-server as described above.  You might be able to force to load
    the module, but it may result in hang-up.   Hence, make sure that
    you load this module *before* X if you encounter this kind of
    problem.

  ------------------

    Module for Yamaha OPL3-SA2/SA3 sound cards.

    autoprobe (if ISA PnP is not used) thus all ports must be specified!!!
