+ This module supports multiple cards and autoprobe.
+
+ Module snd-hda-intel
+ --------------------
+
+ Module for Intel HD Audio (ICH6, ICH6M, ICH7), ATI SB450,
+ VIA VT8251/VT8237A
+
+ 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)
+
+ 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...
