Some platforms may have support for offloading USB audio devices to a dedicated audio DSP. Introduce a set of APIs that allow for management of USB sound card and PCM devices enumerated by the USB SND class driver. This allows for the ASoC components to be aware of what USB devices are available for offloading.

If you want ASoC support, you should say Y here and also to the
|
|
specific driver for your SoC platform below.
|
|
|
|
ASoC provides power efficient ALSA support for embedded battery powered
|
|
SoC based systems like PDA's, Phones and Personal Media Players.
|
|
|
|
This ASoC audio support can also be built as a module. If so, the module
|
|
will be called snd-soc-core.

This option exists to facilitate running the KUnit tests for

the topology core, KUnit is frequently tested in virtual

environments with minimal drivers enabled but the topology

core is usually selected by drivers. There is little reason

to enable it if not doing a KUnit build.

If you want to perform tests on ALSA SoC topology support say Y here.

This builds a module which can be later manually loaded to run KUNIT
|
|
test cases against soc-topology.c API. This should be primarily used
|
|
by developers to test their changes to ASoC.
|
|
|
|
Do note that it creates fake playback devices which do not interact
|
|
well with userspace. When running tests one may want to disable
|
|
userspace applications such as pulseaudio, to prevent unnecessary
|

problems.

help

Enable this option if an ASoC platform card has support to handle
|
|
USB audio offloading. This enables the SoC USB layer, which will
|
|
notify the ASoC USB DPCM backend DAI link about available USB audio
|
|
devices. Based on the notifications, sequences to enable the audio
|
|
stream can be taken based on the design.
