0055 If you don't have a sound card in your computer, you can include a
0056 driver for the PC speaker which allows it to act like a primitive
0057 sound card.
0058 This driver also replaces the pcspkr driver for beeps.
0059
0060 You can compile this as a module which will be called snd-pcsp.
0061
0062 WARNING: if you already have a soundcard, enabling this
0063 driver may lead to a problem. Namely, it may get loaded
0064 before the other sound driver of yours, making the
0065 pc-speaker a default sound device. Which is likely not
0066 what you want. To make this driver play nicely with other
0067 sound driver, you can add this in a configuration file under
0068 /etc/modprobe.d/ directory:
0069 options snd-pcsp index=2
0070
0071 You don't need this driver if you only want your pc-speaker to beep.
0072 You don't need this driver if you have a tablet piezo beeper
0073 in your PC instead of the real speaker.
0074
0075 Say N if you have a sound card.
0076 Say M if you don't.

0211 help
0212 Say Y here to enable the aggressive power-saving support of
0213 AC97 codecs. In this mode, the power-mode is dynamically
0214 controlled at each open/close.
0215
0216 The mode is activated by passing 'power_save=X' to the
0217 snd-ac97-codec driver module, where 'X' is the time-out
0218 value, a nonnegative integer that specifies how many
0219 seconds of idle time the driver must count before it may
0220 put the AC97 into power-save mode; a value of 0 (zero)
0221 disables the use of this power-save mode.
0222
0223 After the snd-ac97-codec driver module has been loaded,
0224 the 'power_save' parameter can be set via sysfs as follows:
0225
0226 echo 10 > /sys/module/snd_ac97_codec/parameters/power_save
0227
0228 In this case, the time-out is set to 10 seconds; setting
0229 the time-out to 1 second (the minimum activation value)
0230 isn't recommended because many applications try to reopen
0231 the device frequently. A value of 10 seconds would be a
0232 good choice for normal operations.
