SOS recommended installation guide

From SpacialAudio

Jump to: navigation, search

The following installation steps outlines the recommended installation guide for SOS.


SOS installation

Download the SOS installation package, either from your secure client section or the SOS public trial download section.

Run the installer and follow the simple installation instructions of the installer. We recommend using all the default settings.


In order to ensure that SOS can automatically recover from a power-failure or system reboot, it is vital that your system should start and automatically log into Windows without ANY user intervention required.

The instructions applies to Windows XP, but may also work for other Windows versions.

  1. Go to the Start Menu and the Run box.
  2. Type in the following:
    control userpasswords2
    now click OK
  3. In the new Windows that appears select the account you wish to make the primary logon.
  4. Now uncheck the "Users must enter a username and password..." box.
  5. Hit Apply and a dialog box will appear asking you to confirm the selected users password.

Click OK when you are done.

SOS auto-start on boot

IMPORTANT: This step must be skipped if you selected the "Auto-restart after reboot" option during the installation process.

Next we make sure SOS automatically starts after each reboot. This is done by adding SOS to the Startup menu.

  1. Open Windows Explorer and browse to the SOS installation folder, usually C:\Program Files\SpacialAudio\SOS.
  2. Right click on sos_autostart.bat and pick Create shortcut from menu.
  3. Now right click on the Start button and pick the Explore option. This will bring up the "Start menu" in Windows Explorer.
  4. Locate the the Startup sub folder.
  5. Now drag the shortcut created in step 2 above to the Startup folder.

SOS configuration

  1. Open up SOS and click on the Config button.
  2. Under the General options tab, make sure Automatically start on load is checked.
    Press OK to save the changes to the configuration.
  3. Now click on the Encoders button to bring up all your configured encoders.
    Double-click on each encoder to open the properties for that encoder and make sure the Auto start encoder after checkbox is checked.

Testing the setup

The final step is to make sure everything is working as expected.

Press the reboot button on your combuter. If everything is configured correctly, the following should happen without ANY user intervention.

  1. Machines restarts and automatically log into Windows (i.e. you do NOT get prompted to enter your username and password)
  2. The SOS application is started automatically.
  3. The SOSChecker application is started automatically.
  4. SOS automatically starts (i.e. the VU meters is showing the input being captured from the soundcard)
  5. SOS automatically starts its encoders, i.e. encoders is showing a status of Encoding...

If you see all of these things happen - then congratulations! You've successfully configured your system to run SOS in the most fault-tolerant setup.

Auto Reboot

To keep SOS in peak performance you should schedule a reboot. This can be as much as you want, we recommend nightly but suggest at least every two days.

To do this, go into your Control Panel and schedule a task for "shutdown -r" (no quotes). Set it for early morning, usually around 2 - 3am. This should not take very long if your computer is fast and doesn't have many processes running.

Do note that you should have auto-login set up on your computer to make this work. If auto-login is not set, your computer will reboot and stay at the login prompt, not restarting SOS.

Optional - SOSChecker setup

Open SOSChecker and change the configuration for each error event type. These settings will depend on your specific recovery needs, so no recommended setup currently provided. The default SOSChecker configuration should cover the most basic errors though.

One recommendation we can make though is to set the Audio check type to Reboot machine on Action 3. That way if SOS is unable to grab a hold of the soundcard device in 3 tries, then the whole machine will be rebooted to give SOS a chance to try again after the reboot.
