9 Troubleshooting
There is an error message during the driver installation:
1. Verify that the LT-TB has been installed correctly and there is an LED flashing on the
LT-TB board when unplugged. The LED should go solid when a Thunderbolt cable is
connected. See
Section 5 .3: Installing the Lynx Driver .
2. Verify that the TB cable is connected correctly and that the computer TB ports are active
and the drivers are functional.
3. Verify that your Aurora has firmware revision 28 or above
The LT-TB does not show up in the Operating System as a usable device:
1. Check that the LT-TB is correctly installed and verify that the green LED (D30) on the
LT-TB is flashing.
2. Close the Lynx Mixer and any audio applications and reset the LT-TB either by removing
then reinserting the TB cable, or by turning the Aurora off for 5 seconds, then turning it
back on.
3. Verify that the Aurora has firmware revision 28 or above. To determine what firmware
revision your Aurora has, press the TRIM and POWER buttons at the same time with the
power to the Aurora off. If the LED flashes over the numbers 2 on the input row & 8 on
the output row or above (i.e. 2&9, 3&0, etc.) in the Aurora Meter Display, then your unit
is compatible with the LT-TB. If pressing Power and Trim does not cause any LEDs to
flash, causes a sequence lower than 28 to flash, or causes a single number to flash, then
your unit needs to be updated.
4. Check that the OS is compatible with the LT-TB. One must be running OS X 10.8.5+ or
Windows 7 or 8 (32-bit or 64-bit).
The Aurora shows up in the Operating System as a usable device, but will not pass
audio:
1. Make sure that the LT-TB has been assigned as the active device in the application being
tested. Many audio applications allow a specific audio device to be selected from a
configuration menu. Other applications will use whatever the operating system default
device is. In this case verify that the Aurora has been configured as the default playback
device for the system.
2. Check that the source for TO ANALOG OUT is set to “LSLOT IN”.
3. Check the Lynx Mixer Outputs Panel and see if there is meter activity for the appropriate
outputs being used. If there is, check the cable connections from the Aurora analog or
digital outputs to the monitoring equipment.
4. Click “Restore Defaults” in the Lynx Mixer.
5. Close the Lynx Mixer and any audio applications and reset the LT-TB either by removing
then reinserting the thunderbolt cable, or by turning the Aurora off for 5 seconds, then
turning it back on.
6. Verify that the Aurora has firmware revision 28 or above. To determine what firmware
revision your Aurora has, press the TRIM and POWER buttons at the same time with the
power to the Aurora off. If the LED flashes over the numbers 2 on the input row & 8 on
the output row or above (i.e. 2&9, 3&0, etc.) in the Aurora Meter Display, then your unit
