The following instructions show how to set up system audio playback through a StudioLive RM32Ai or RM16Ai mixer on Windows 7 or 8 using the WDM audio drivers
****NOTE: It is highly recommended that you use the latest firmware and Universal Control AI version from your Presonus User Account and from Product Downloads for the RM mixer Series.
NOTE: Compatibility with PC computers must meet certain criteria for audio passing over firewire. Please see the below knowledge base on how to properly connect a StudioLive mixer to a PC computer:
How do I properly connect my StudioLive to my PC?
Set the RM series mixer as the Playback device (Windows Sound Setup)
First, to route audio through your StudioLive RM series mixer to play back general system sounds (i.e. YouTube, iTunes, etc.) you will need to set it up as the default playback device:
1. Right-click on the Speaker in the System Tray of Windows and click "Playback devices."
2. The RM series mixers are part of the FireStudio family of firewire interfaces. On the Playback tab, click on the "Presonus FireStudio" device and click "Set Default." Then, click "Ok."
All Audio Playback from WDM applications and your Windows System Sound will now be routed to your RM series mixer. Please see Sections A and B below for the two different suggested routing setups.
*****************************************************
A) Playing audio through default playback channels 1 and 2
NOTE: By default, your Windows system sound will use the first two channels of the configured audio device as playback channels, so by default, playback will go to channels 1 and 2 of your mixer
1. Open Universal Control AI and click on your StudioLive RM mixer tab to open UC Surface
NOTE: If you see your mixer listed in Universal Control AI with a "Wireless" 
icon, then your mixer is not being seen as connected via FireWire. Please check the article below to verify and troubleshoot that your mixer is connected and functioning on your computer:

2. Select Channel 1, then press the Channel Options view (small gear symbol)
3. Select the "Digital" source in the channel select tab, press the "Link" button to link mixer channels 1 and 2, and test the playback audio through your system.
NOTE: If you are having problems with audio passing, see the links below for general issues that can occur with connecting a mixer via firewire and audio does not pass correctly.
