41 If you don't have a sound card in your computer, you can include a
42 driver for the PC speaker which allows it to act like a primitive
43 sound card.
44 This driver also replaces the pcspkr driver for beeps.
45
46 You can compile this as a module which will be called snd-pcsp.
47
48 WARNING: if you already have a soundcard, enabling this
49 driver may lead to a problem. Namely, it may get loaded
50 before the other sound driver of yours, making the
51 pc-speaker a default sound device. Which is likely not
52 what you want. To make this driver play nicely with other
Lucas De Marchi970e2482012-03-30 13:37:16 -070053 sound driver, you can add this in a configuration file under
54 /etc/modprobe.d/ directory:
Takashi Iwai89fe5112008-05-23 16:10:37 +020055 options snd-pcsp index=2
56
57 You don't need this driver if you only want your pc-speaker to beep.
58 You don't need this driver if you have a tablet piezo beeper
59 in your PC instead of the real speaker.
60
61 Say N if you have a sound card.
62 Say M if you don't.
63 Say Y only if you really know what you do.

189 Say Y here to enable the aggressive power-saving support of

191 controlled at each open/close.
192
Michael Witten1d8c1102010-07-14 23:54:21 +0000193 The mode is activated by passing 'power_save=X' to the
194 snd-ac97-codec driver module, where 'X' is the time-out
195 value, a nonnegative integer that specifies how many
196 seconds of idle time the driver must count before it may
197 put the AC97 into power-save mode; a value of 0 (zero)
198 disables the use of this power-save mode.
199
200 After the snd-ac97-codec driver module has been loaded,
201 the 'power_save' parameter can be set via sysfs as follows:
202
203 echo 10 > /sys/module/snd_ac97_codec/parameters/power_save
204
205 In this case, the time-out is set to 10 seconds; setting
206 the time-out to 1 second (the minimum activation value)
207 isn't recommended because many applications try to reopen
208 the device frequently. A value of 10 seconds would be a
209 good choice for normal operations.
