| 52 | If you don't have a sound card in your computer, you can include a |
| 53 | driver for the PC speaker which allows it to act like a primitive |

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

| 204 | controlled at each open/close. |
| 205 | |
| 206 | The mode is activated by passing 'power_save=X' to the |
| 207 | snd-ac97-codec driver module, where 'X' is the time-out |
| 208 | value, a nonnegative integer that specifies how many |
| 209 | seconds of idle time the driver must count before it may |
| 210 | put the AC97 into power-save mode; a value of 0 (zero) |
| 211 | disables the use of this power-save mode. |
| 212 | |
| 213 | After the snd-ac97-codec driver module has been loaded, |
| 214 | the 'power_save' parameter can be set via sysfs as follows: |

| 218 | In this case, the time-out is set to 10 seconds; setting |
| 219 | the time-out to 1 second (the minimum activation value) |
| 220 | isn't recommended because many applications try to reopen |
| 221 | the device frequently. A value of 10 seconds would be a |
