Audio troubleshooting tips

Summary

Installing the Correct AJA card drivers and firmware

Check that your workstation has the correct version of tha AJA card driver and firmware.

• On Linux workstations, install the correct version of the Discreet Kernel Utilities (DKU). The DKU automatically installs the AJA driver.
  Refer to the Release Notes for information on the DKU version you should install, as well as on checking and updating the AJA card firmware.

• On Mac OS X workstations, install the AJA driver version specified on the Autodesk Smoke System Requirements Web Page.

Configuring Mac OS X system sound preferences

Incorrect system sound preferences are a common cause of audio issues in Smoke for Mac OS X.

1. Open System Preferences > Sound.
    
2. Make sure that Sound Effects, Input and Output are set to something else than "AJA Kona 3", such as "Internal speakers".

Using Smoke for Mac OS X without an AJA card

If your Mac OS X workstation does not have an AJA card, perform the following tasks to enable sound in Smoke:

1. Open the Smoke Setup utility from the Applications / Autodesk / Smoke <version number> / Utilities folder.

2. Make sure the video device is set to "none" and the audio device is set to "CoreAudio" in the General tab.

Troubleshooting Embedded Audio

If your application is experiencing problems with embedded audio, check the following items:

• Can you detect the video signal?
   
• Check that the Autodesk application is correctly set up to use embedded audio:

1. Go to Preferences >> Audio >> Inputs >> Embedded.
    
2. Make sure this setting is not "AES-BNC" or "AES-XLR".

Troubleshooting AES / EBU

AES Input
If your application is experiencing problems with AES audio on INPUT , check the following items:

• Check that the Autodesk application is correctly set up to use AES audio:

1. Go to Preferences >> Audio >> Inputs >> AES-XLR.

2. Make sure this setting is not "Embedded"  or "AES-BNC".

• Check that the 48khz sampling rate light is GREEN . If the light is RED , either the AES input is not reconized by the AJA BOB (unplugged) or is getting the wrong sampling rate from the device connected.

AES Output
If your application is experiencing problems with AES audio on OUTPUT , check the following items:

• Check that the converter is set to "AES IN -to AES OUT":
  Go to ADAT Converter Settings on the front of the device , or set the appropriate dipswitch on the rear of the unit. (see the user manual for dipswitch setup)

• Do you see any signal on the front of the Lucid converter ?
  
  Check the wiring for a valid AES signal and set the lucid to "AES  in -to- Meters out".

Troubleshooting Analog Monitoring

If your application is experiencing problems with analog monitoring, check the following items:

• From the AJA Break out box AES outputs, 110 ohm Digital XLR cables should connect to the Lucid's AES inputs.
   
• From the Lucid Audio converter's Analog XLR  , standard analog XLR cables should connect to your monitoring system.
   
• The Lucid's internal settings should always be set to "AES in -to- ANALOG out".
   
• Verify that the Lucid is recieving audio by cheking the VU meters on the front of the unit ( Lucid in ''METERS AES in '' mode ).
