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. | |

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 |

118 | This driver is aimed at extended testing of the userspace applications | |

120 | ||
121 | It can generate random or pattern-based data into the capture stream, | |

123 | time delays during capture/playback, redefine the RESET ioctl operation | |
124 | to perform the PCM middle layer testing and inject errors during the | |

235 | ||
1d8c1100 MW |
236 | The mode is activated by passing 'power_save=X' to the |
237 | snd-ac97-codec driver module, where 'X' is the time-out | |
238 | value, a nonnegative integer that specifies how many | |
239 | seconds of idle time the driver must count before it may | |
240 | put the AC97 into power-save mode; a value of 0 (zero) | |
241 | disables the use of this power-save mode. | |
242 | ||
243 | After the snd-ac97-codec driver module has been loaded, | |
244 | the 'power_save' parameter can be set via sysfs as follows: | |

246 | echo 10 > /sys/module/snd_ac97_codec/parameters/power_save | |

248 | In this case, the time-out is set to 10 seconds; setting | |
249 | the time-out to 1 second (the minimum activation value) | |
250 | isn't recommended because many applications try to reopen | |
