54 | help |
55 | If you don't have a sound card in your computer, you can include a | |
56 | driver for the PC speaker which allows it to act like a primitive | |
57 | sound card. | |
58 | This driver also replaces the pcspkr driver for beeps. | |
59 | ||
60 | You can compile this as a module which will be called snd-pcsp. | |
61 | ||
3ccee690 SS |
62 | WARNING: if you already have a soundcard, enabling this |
63 | driver may lead to a problem. Namely, it may get loaded | |
64 | before the other sound driver of yours, making the | |
65 | pc-speaker a default sound device. Which is likely not | |
66 | what you want. To make this driver play nicely with other | |
970e2486 LDM |
67 | sound driver, you can add this in a configuration file under |
68 | /etc/modprobe.d/ directory: | |
3ccee690 SS |
69 | options snd-pcsp index=2 |
70 | ||
9ab4d072 SS |
71 | You don't need this driver if you only want your pc-speaker to beep. |
72 | You don't need this driver if you have a tablet piezo beeper | |
73 | in your PC instead of the real speaker. | |

204 | help | |
205 | Say Y here to enable the aggressive power-saving support of | |
206 | AC97 codecs. In this mode, the power-mode is dynamically | |
207 | controlled at each open/close. | |
208 | ||
1d8c1100 MW |
209 | The mode is activated by passing 'power_save=X' to the |
210 | snd-ac97-codec driver module, where 'X' is the time-out | |
211 | value, a nonnegative integer that specifies how many | |
212 | seconds of idle time the driver must count before it may | |
213 | put the AC97 into power-save mode; a value of 0 (zero) | |
214 | disables the use of this power-save mode. | |
215 | ||
216 | After the snd-ac97-codec driver module has been loaded, | |
217 | the 'power_save' parameter can be set via sysfs as follows: | |
218 | ||
219 | echo 10 > /sys/module/snd_ac97_codec/parameters/power_save | |
220 | ||
221 | In this case, the time-out is set to 10 seconds; setting | |
222 | the time-out to 1 second (the minimum activation value) | |
223 | isn't recommended because many applications try to reopen | |
224 | the device frequently. A value of 10 seconds would be a | |
225 | good choice for normal operations. | |
