| 6 | Support making sounds through an audio codec. This is normally a |
| 7 | beep at a chosen frequency for a selected length of time. However |
| 8 | the drivers support playing arbitrary sound samples using a |
| 9 | PCM interface. |
| 10 | |
| 11 | Note: At present the sound setup is somewhat tangled up in that the |
| 12 | audio codecs are called from the sound-i2s code. This could be |
| 13 | converted to driver model. |

| 18 | help |
| 19 | I2S is a serial bus often used to transmit audio data from the |
| 20 | SoC to the audio codec. This option enables sound support using |
| 21 | I2S. It calls either of the two supported codecs (no use is made |
| 22 | of driver model at present). |

| 29 | audio codec. This option enables support for this, using one of the |
| 30 | available audio codec drivers. This driver does not make use of |
| 31 | DMA, but writes each word directly to the hardware. |

| 38 | data to an audio codec. This option enables support for this, |
| 39 | using one of the available audio codec drivers. Enabling this |
| 40 | option provides an implementation for sound_init() and |
| 41 | sound_play(). |

| 46 | help |
| 47 | This enables support for a beeper that uses the i8254 timer chip. |
| 48 | This can emit beeps at a fixed frequency. It is possible to control |
| 49 | the length of the beeps, by turning a beep on, waiting for a period |
| 50 | of time, then turning it off. |
| 51 | |
| 52 | This is quite an old feature, called PIT (Programmable Interval |
| 53 | Timer), but is nonetheless still available on modern x86 machines. |
