| 23 | help | |
| 24 | Say Y or M to enable MIDI sequencer and router support. This | |
| 25 | feature allows routing and enqueueing of MIDI events. Events | |
| 26 | can be processed at a given time. | |
| 27 | ||
| 28 | Many programs require this feature, so you should enable it | |
| 29 | unless you know what you're doing. | |
| 30 | ||
| 31 | config SND_SEQ_DUMMY | |
| 32 | tristate "Sequencer dummy client" | |
| 33 | depends on SND_SEQUENCER | |
| 34 | help | |
| 35 | Say Y here to enable the dummy sequencer client. This client | |
| 36 | is a simple MIDI-through client: all normal input events are | |
| 37 | redirected to the output port immediately. | |
| 38 | ||
| 39 | You don't need this unless you want to connect many MIDI | |
| 40 | devices or applications together. | |
| 41 | ||
| 42 | To compile this driver as a module, choose M here: the module | |
| 43 | will be called snd-seq-dummy. | |

| 52 | select SND_OSSEMUL | |
| 53 | help | |
| 54 | To enable OSS mixer API emulation (/dev/mixer*), say Y here | |
| 55 | and read <file:Documentation/sound/alsa/OSS-Emulation.txt>. | |
| 56 | ||
| 57 | Many programs still use the OSS API, so say Y. | |
| 58 | ||
| 59 | To compile this driver as a module, choose M here: the module | |
| 60 | will be called snd-mixer-oss. | |

| 68 | To enable OSS digital audio (PCM) emulation (/dev/dsp*), say Y | |
| 69 | here and read <file:Documentation/sound/alsa/OSS-Emulation.txt>. | |
| 70 | ||
| 71 | Many programs still use the OSS API, so say Y. | |

| 79 | select SND_OSSEMUL | |
| 80 | help | |
| 81 | Say Y here to enable OSS sequencer emulation (both | |
| 82 | /dev/sequencer and /dev/music interfaces). | |
| 83 | ||
| 84 | Many programs still use the OSS API, so say Y. | |
| 85 | ||
| 86 | To compile this driver as a module, choose M here: the module | |
| 87 | will be called snd-seq-oss. | |

| 89 | config SND_RTCTIMER | |
| 90 | tristate "RTC Timer support" | |
| 91 | depends on SND && RTC | |
| 92 | select SND_TIMER | |
| 93 | help | |
| 94 | Say Y here to enable RTC timer support for ALSA. ALSA uses | |
| 95 | the RTC timer as a precise timing source and maps the RTC | |
| 96 | timer to ALSA's timer interface. The ALSA sequencer code also | |
| 97 | can use this timing source. | |
| 98 | ||
| 99 | To compile this driver as a module, choose M here: the module | |
| 100 | will be called snd-rtctimer. | |

| 104 | depends on SND_RTCTIMER && SND_SEQUENCER | |
| 105 | default y | |
| 106 | help | |
| 107 | Say Y here to use the RTC timer as the default sequencer | |
| 108 | timer. This is strongly recommended because it ensures | |
| 109 | precise MIDI timing even when the system timer runs at less | |
| 110 | than 1000 Hz. | |
| 111 | ||
| 112 | If in doubt, say Y. | |

| 118 | Say Y here to enable verbose log messages. These messages | |
| 119 | will help to identify source file and position containing | |
| 120 | printed messages. | |
| 121 | ||
| 122 | You don't need this unless you're debugging ALSA. | |
