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

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