  Module snd-hda-intel
  --------------------

    Module for Intel HD Audio (ICH6, ICH6M, ESB2, ICH7, ICH8),
		ATI SB450, SB600, RS600,
		VIA VT8251/VT8237A,
		SIS966, ULI M5461

    model	- force the model name
    position_fix - Fix DMA pointer (0 = auto, 1 = none, 2 = POSBUF, 3 = FIFO size)
    single_cmd  - Use single immediate commands to communicate with
		codecs (for debugging only)
    disable_msi - Disable Message Signaled Interrupt (MSI)

    This module supports one card and autoprobe.

    Each codec may have a model table for different configurations.
    If your machine isn't listed there, the default (usually minimal)
    configuration is set up.  You can pass "model=<name>" option to
    specify a certain model in such a case.  There are different
    models depending on the codec chip.

    If the default configuration doesn't work and one of the above
    matches with your device, report it together with the PCI
    subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel
    ML (see the section "Links and Addresses").

    Note 2: If you get click noises on output, try the module option
	    position_fix=1 or 2.  position_fix=1 will use the SD_LPIB
	    register value without FIFO size correction as the current
	    DMA pointer.  position_fix=2 will make the driver to use
	    the position buffer instead of reading SD_LPIB register.
	    (Usually SD_LPLIB register is more accurate than the
	    position buffer.)

    NB: If you get many "azx_get_response timeout" messages at
    loading, it's likely a problem of interrupts (e.g. ACPI irq
    routing).  Try to boot with options like "pci=noacpi".  Also, you
    can try "single_cmd=1" module option.  This will switch the
    communication method between HDA controller and codecs to the
    single immediate commands instead of CORB/RIRB.  Basically, the
    single command mode is provided only for BIOS, and you won't get
    unsolicited events, too.  But, at least, this works independently
    from the irq.  Remember this is a last resort, and should be
    avoided as much as possible...
