-To launch the application the user touches the Audio Controls button (speaker icon) at the top of the device, or launch through the Application Screen.
-To adjust the sliders, the user must touch the small ball adjacent to the slider and drag vertically; touching the slider at other points will not adjust the slider’s position.
-===== Technical Details  =====
-The sections below are taken from directions for what is known as the Tizen IVI 3.0-M2-EOY (commonly called 'the Jan. 15 image'.  The current Tizen release is dated 2014.01.14, and may require some adjustment.
-==== Installation Prerequisites  ====
-The following installation directions take the base Tizen image and install needed supporting software
-==== Audio Controls Application  ====
-=== Tizen Audio Output Configuration  ===
-Execute the command (one time only):
-  root:~> alsactl init 0
-This enables audio generated from the Audio Controls application to be available on the Line Out Jack.
-=== WRT Plugin Dependencies  ===
-Depends on installation of the MOST WRT plugin, which is  rpm packages wrt-plugins-ivi-most-0.8.6-1.i586 and wrt-plugins-ivi-most-devel-0.8.6-1.i586.
-==== Instructions for debugging WRT Apps on Tizen IVI (installation, removal, and deployment)  ====
-Tizen IVI WRT applications are built into widget ('.wgt') files for deployment (a format based on the %%W3C%% widget specification, see http://www.w3.org/TR/widgets/ for more information). Once you have built or received the widget files for one or more applications that you wish to deploy and run, the next step is to copy them onto the target device. Common options for this would be tools like scp/sftp (in a Linux/Unix environment), FileZilla (Windows and Mac) or Cyberduck (Mac).
-Once the .wgt files have been transferred to the target machine, they may be installed, launched and uninstalled.
-To get a list of currently installed applications, use the following command from a terminal (or remote shell/ssh session) on the target hardware (log in as root with the password tizen):
-  root:~> wrt-launcher -l
-This will produce output similar to the following:
-| **No**| **Name **  | **Version**| **GUID**                            | **Package ID**| **App ID** |
-| 1     | saythis    | 1.0.0      | %%http://yourdomain/sayThis%%       | lYjFlj49Q4    | lYjFlj49Q4.saythis |
-| 2     | Settings   | 1.0.0      | %%http://yourdomain/Settings%%      | ODBQpKvkS1    | ODBQpKvkS1.Settings |
-| 3     | MediaPlayer| 1.0.0      | %%http://yourdomain/MediaPlayer%%   |t8j6HTRpuz     | t8j6HTRpuz.MediaPlayer|
-| 4     |Store       |8.2.4401    | %%http://com.intel.tizen/store%%    | intelPoc13    | intelPoc13.Store |
-| 5     | Phone      | 8.2.4399   | %%http://com.intel.tizen/phone%%    | intelPoc15    | intelPoc15.phone |
-If the application you wish to install is not already installed, simply enter (using intelPoc16.HVAC.wgt as an example):
-  root:~> wrt-installer -i intelPoc16.HVAC.wgt
-If successful, you should see output such as the following:
-  ===========================================================
-     # wrt-installer #
-     # argc [3]
-     # argv[0] = [wrt-installer]
-     # argv[1] = [-i]
-     # argv[2] = [intelPoc16.HVAC.wgt]
-     ## wrt-installer : intelPoc20.AudioNonPOC installation was successful.
-     ===========================================================
-If unsuccessful, you may see errors such as 'invalid widget package', 'privilege level violation' or, if the application is already installed (and its widget file was built with a different signature than the one you wish to install), 'invalid signature'. The first two errors are out of scope for this document.
-If you see 'invalid signature', and the widget file has to your knowledge been created with a valid signature, the likely cause is a conflict between the signature of the currently installed version and that of the new version. Though both signatures may be valid, the system treats the upgrade of an existing package with a different signature as a security violation. To work around this issue, simply uninstall the application and subsequently install the new version:
-  root:~> wrt-installer -un intelPoc20.AudioNonPOC      <-- note: use the App ID when
-  un-installing and the full widget filename when installing
-If the uninstall is successful, you should see output like the following:
-  ===========================================================
-     # wrt-installer #
-     # argc [3]
-     # argv[0] = [wrt-installer]
-     # argv[1] = [-un]
-     # argv[2] = [intelPoc20.AudioNonPOC]
-     ===========================================================
-     ## wrt-installer : intelPoc20.AudioNonPOC uninstallation was successful.
-Refer to installation instructions above for the subsequent installation steps.
-In order to launch and run an installed application, issue the following command with the application's App ID as an argument:
-  root:~> wrt-launcher -s intelPoc20.AudioNonPOC
-You should see the application start and run on the target device.
-To launch the application in debug mode, add the '-d' flag:
-  root:~> wrt-launcher -d -s intelPoc20.AudioNonPOC
-This will produce output like the following:
-  root:~/wgt> wrt-launcher -d -s intelPoc20.AudioNonPOC
-     port: 36070
-     result: launched
-The port number referenced is a random high port which allows one to connect to the target device with a web browser using a %%URL%% of the form:
-  http://&lt;ip address or name of target device>:<port #>
-**For example:**
-  http://192.168.1.223:36070
-Once connected, you should see a single link in the upper right of the resulting web page, e.g.:
-  file:///opt/usr/apps/intelPoc20/res/wgt/index.html
-Clicking that link will launch Webkit Web Inspector, a set of web development tools that should look familiar to users of Firefox Firebug or Chrome Dev Tools. Click the 'Console' icon in the toolbar to go to the Javascript console. Press ctrl-R, or type:
-  window.location.reload();
-...to reload the application in order to display the startup/initialization functions associated with the app (since the app has already started by the time the debug interface is available).
-To exit a running application, issue the following command with the application's App ID as an argument:
-  root:~> wrt-launcher -k intelPoc20.AudioNonPOC
-**Instruction to the console:**
-Assumptions these are all running from the Tizen platform and can access the console by SSH command or Control ALT F4 for a terminal. Tizen instructions are at Tizen.org
-Install
-  wrt-installer -i intelPoc20.AudioNonPOC.wgt
-Launch
-  wrt-installer -i intelPoc20.AudioNonPOC.wgt
