isapnp - ISA PnP detection - 0 = disable, 1 = enable (default)
The below are options for wavefront_synth features:
wf_raw - Assume that we need to boot the OS (default:no)
If yes, then during driver loading, the state of the board is
ignored, and we reset the board and load the firmware anyway.
fx_raw - Assume that the FX process needs help (default:yes)
If false, we'll leave the FX processor in whatever state it is
when the driver is loaded. The default is to download the
microprogram and associated coefficients to set it up for
"default" operation, whatever that means.
debug_default - Debug parameters for card initialization
wait_usecs - How long to wait without sleeping, usecs
(default:150)
This magic number seems to give pretty optimal throughput
based on my limited experimentation.
If you want to play around with it and find a better value, be
my guest. Remember, the idea is to get a number that causes us
to just busy wait for as many WaveFront commands as possible,
without coming up with a number so large that we hog the whole
CPU.
Specifically, with this number, out of about 134,000 status
waits, only about 250 result in a sleep.
sleep_interval - How long to sleep when waiting for reply
(default: 100)
sleep_tries - How many times to try sleeping during a wait
(default: 50)
ospath - Pathname to processed ICS2115 OS firmware
(default:wavefront.os)
The path name of the ISC2115 OS firmware. In the recent
version, it's handled via firmware loader framework, so it
must be installed in the proper path, typically,
/lib/firmware.
reset_time - How long to wait for a reset to take effect
(default:2)
ramcheck_time - How many seconds to wait for the RAM test
(default:20)
osrun_time - How many seconds to wait for the ICS2115 OS
(default:10)
This module supports multiple cards and ISA PnP.
Note: the firmware file "wavefront.os" was located in the earlier
version in /etc. Now it's loaded via firmware loader, and
must be in the proper firmware path, such as /lib/firmware.
Copy (or symlink) the file appropriately if you get an error
regarding firmware downloading after upgrading the kernel.

Notes on Power-Saving Mode
==========================
AC97 and HD-audio drivers have the automatic power-saving mode.
This feature is enabled via Kconfig CONFIG_SND_AC97_POWER_SAVE
and CONFIG_SND_HDA_POWER_SAVE options, respectively.
With the automatic power-saving, the driver turns off the codec power
appropriately when no operation is required. When no applications use
the device and/or no analog loopback is set, the power disablement is
done fully or partially. It'll save a certain power consumption, thus
good for laptops (even for desktops).
The time-out for automatic power-off can be specified via power_save
module option of snd-ac97-codec and snd-hda-intel modules. Specify
the time-out value in seconds. 0 means to disable the automatic
power-saving. The default value of timeout is given via
CONFIG_SND_AC97_POWER_SAVE_DEFAULT and
CONFIG_SND_HDA_POWER_SAVE_DEFAULT Kconfig options. Setting this to 1
(the minimum value) isn't recommended because many applications try to
reopen the device frequently. 10 would be a good choice for normal
operations.
The power_save option is exported as writable. This means you can
adjust the value via sysfs on the fly. For example, to turn on the
automatic power-save mode with 10 seconds, write to
/sys/modules/snd_ac97_codec/parameters/power_save (usually as root):
# echo 10 > /sys/modules/snd_ac97_codec/parameters/power_save
Note that you might hear click noise/pop when changing the power
state. Also, it often takes certain time to wake up from the
power-down to the active state. These are often hardly to fix, so
don't report extra bug reports unless you have a fix patch ;-)
For HD-audio interface, there is another module option,
power_save_controller. This enables/disables the power-save mode of
the controller side. Setting this on may reduce a bit more power
consumption, but might result in longer wake-up time and click noise.
Try to turn it off when you experience such a thing too often.
