+config SOUND_DA7219
+ bool "Dialog Semiconductor audio codec"
+ depends on SOUND
+ help
+ The DA7219 is an ultra-low-power audio codec with Advanced Accessory
+ Detection (AAD). This driver only supports generation of ACPI tables.
+ It does not support sound output or any of the other codec
+ features.

+config SOUND_I8254
+ bool "Intel i8254 timer / beeper"
+ depends on SOUND
+ help
+ This enables support for a beeper that uses the i8254 timer chip.
+ This can emit beeps at a fixed frequency. It is possible to control
+ the length of the beeps, by turning a beep on, waiting for a period
+ of time, then turning it off.
+
+ This is quite an old feature, called PIT (Programmable Interval
+ Timer), but is nonetheless still available on modern x86 machines.

+ select TEGRA124_DMA
+ help
+ Nvidia Tegra SoCs support several I2S interfaces for sending audio
+ data to an audio codec. This option enables support for this,
+ using one of the available audio codec drivers.
