/*! \page Usecase ALSA Use Case Interface
*
* The use case manager works by configuring the sound card ALSA kcontrols to
* change the hardware digital and analog audio routing to match the requested
* device use case. The use case manager kcontrol configurations are stored in
* easy to modify text files.
*
* An audio use case can be defined by a verb and device parameter. The verb
* describes the use case action i.e. a phone call, listening to music, recording
* a conversation etc. The device describes the physical audio capture and playback
* hardware i.e. headphones, phone handset, bluetooth headset, etc.
*
* It's intended clients will mostly only need to set the use case verb and
* device for each system use case change (as the verb and device parameters
* cover most audio use cases).
*
* However there are times when a use case has to be modified at runtime. e.g.
*
* + Incoming phone call when the device is playing music
* + Recording sections of a phone call
* + Playing tones during a call.
*
* In order to allow asynchronous runtime use case adaptations, we have a third
* optional modifier parameter that can be used to further configure
* the use case during live audio runtime.
*
* This interface allows clients to :-
*
* + Query the supported use case verbs, devices and modifiers for the machine.
* + Set and Get use case verbs, devices and modifiers for the machine.
* + Get the ALSA PCM playback and capture device PCMs for use case verb,
* use case device and modifier.
* + Get the TQ parameter for each use case verb, use case device and
* modifier.
* + Get the ALSA master playback and capture volume/switch kcontrols
* for each use case.

*
* Note: The returned string is dynamically allocated, use free() to
* deallocate this string. (Yes, the value parameter shouldn't be marked as
* "const", but it's too late to fix it, sorry about that.)
*
* Known identifiers:
* - NULL - return current card
* - _verb - return current verb
* - _file - return configuration file loaded for current card
*
* - [=]{NAME}[/[{modifier}|{/device}][/{verb}]]
* - value identifier {NAME}
* - Search starts at given modifier or device if any,
* else at a verb
* - Search starts at given verb if any,
* else current verb
* - Searches modifier/device, then verb, then defaults
* - Specify a leading "=" to search only the exact
* device/modifier/verb specified, and not search
* through each object in turn.
* - Examples:
* - "PlaybackPCM/Play Music"
* - "CapturePCM/SPDIF"
* - From ValueDefaults only:
* "=Variable"
* - From current active verb:
* "=Variable//"
* - From verb "Verb":
* "=Variable//Verb"
* - From "Modifier" in current active verb:
* "=Variable/Modifier/"
* - From "Modifier" in "Verb":
* "=Variable/Modifier/Verb"
*
* Recommended names for values:
* - TQ
* - Tone Quality
* - PlaybackPCM
* - full PCM playback device name
* - PlaybackPCMIsDummy
* - Valid values: "yes" and "no". If set to "yes", the PCM named by the
* PlaybackPCM value is a dummy device, meaning that opening it enables
* an audio path in the hardware, but writing to the PCM device has no
* effect.
* - CapturePCM
* - full PCM capture device name
* - CapturePCMIsDummy
* - Valid values: "yes" and "no". If set to "yes", the PCM named by the
* CapturePCM value is a dummy device, meaning that opening it enables
* an audio path in the hardware, but reading from the PCM device has no
* effect.
* - PlaybackRate
* - playback device sample rate
* - PlaybackChannels
* - playback device channel count
* - PlaybackCTL
* - playback control device name
* - PlaybackVolume
* - playback control volume ID string
* - PlaybackSwitch
* - playback control switch ID string
* - CaptureRate
* - capture device sample rate
* - CaptureChannels
* - capture device channel count
* - CaptureCTL
* - capture control device name
* - CaptureVolume
* - capture control volume ID string
* - CaptureSwitch
* - capture control switch ID string
* - PlaybackMixer
* - name of playback mixer
* - PlaybackMixerID
* - mixer playback ID
* - CaptureMixer
* - name of capture mixer
* - CaptureMixerID
* - mixer capture ID
* - JackControl, JackDev, JackHWMute
* - Jack information for a device. The jack status can be reported via
* a kcontrol and/or via an input device. **JackControl** is the
* kcontrol name of the jack, and **JackDev** is the input device id of
* the jack (if the full input device path is /dev/input/by-id/foo, the
* JackDev value should be "foo"). UCM configuration files should
* contain both JackControl and JackDev when possible, because
* applications are likely to support only one or the other.
*
* If **JackHWMute** is set, it indicates that when the jack is plugged
* in, the hardware automatically mutes some other device(s). The
* JackHWMute value is a space-separated list of device names (this
* isn't compatible with device names with spaces in them, so don't use
* such device names!). Note that JackHWMute should be used only when
* the hardware enforces the automatic muting. If the hardware doesn't
* enforce any muting, it may still be tempting to set JackHWMute to
* trick upper software layers to e.g. automatically mute speakers when
* headphones are plugged in, but that's application policy
* configuration that doesn't belong to UCM configuration files.
