| 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. | |
| Say Y only if you really know what you do. | |

| help | |
| Say 'Y' or 'M' to include support for the PCM loopback device. | |
| This module returns played samples back to the user space using | |
| the standard ALSA PCM device. The devices are routed 0->1 and | |
| 1->0, where first number is the playback PCM device and second | |
| number is the capture device. Module creates two PCM devices and | |
| configured number of substreams (see the pcm_substreams module | |
| parameter). | |
| The loopback device allows time synchronization with an external | |
| timing source using the time shift universal control (+-20% | |
| of system time). | |

| will be called snd-aloop. | |

| Say 'Y' or 'M' to include support for the Virtual PCM test driver. | |
| This driver is aimed at extended testing of the userspace applications | |
| which use the ALSA API, as well as the PCM middle layer testing. | |
| It can generate random or pattern-based data into the capture stream, | |
| check the playback stream for containing the selected pattern, inject | |
| time delays during capture/playback, redefine the RESET ioctl operation | |
| to perform the PCM middle layer testing and inject errors during the | |
| PCM callbacks. It supports both interleaved and non-interleaved access | |
| modes. You can find the corresponding selftest in the 'alsa' | |
| selftests folder. | |

| 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. | |
