Rebooting the Sound Server

If the Sound Server is not Rebooted Properly You Will Hear Bursts of Static

If the Sound Server is not rebooted properly you will hear bursts of static coming out of the speakers every few seconds when running the sound server.  This is because when  the sound server and/or the audio matrix are rebooted or restarted, the drivers need to be reset for the audio card connected to the sound server.

Why you ask? A bit of background will make you more informed. In the digital audio world, digital audio needs to sync to a clock source so it plays back the audio at a consistent speed. The MOTU cards can get their sync from their PCI card (called ‘Internal’), or via an outside source, such as another audio card, or some master clock. In one system, however, there can be only one clock source. In our system, the sound server sends audio to the audio matrix via a digital connection, so one machine must be slaved to the other. If not, then both compete for time control, which you will hear as short bursts of static whenever both sources are playing. Our system needs to be set-up so that the sound server is slaved to the audio matrix.

How to Slave the Sound Server to the Audio Matrix

Below are the instructions on how to slave the sound server to the audio matrix.

  1. Load the MOTU PCI Audio Console


     

  2. Click on the microphone icon and you will get the following screen.


     

  3. Do NOT adjust anything but the Clock Source. Click the Clock Source pull-down menu and select 2408: Bank A Optical, as shown below.


     

  4. Quit the MOTU PCI console. You will not need to reset this as long as the machine is up and running.
