Troubleshooting
I cannot record from the LynxONE’s digital input.
The LynxONE Digital Input device must be configured as the record device in your
application. Select this device in the audio or wave device configuration menu. With
the device properly set, the meters in the LynxONE mixer will indicate the digital input
signal level while recording. See “Working with Third Party Applications” for more
information.
There is no signal on the digital output during playback.
The LynxONE Digital Output device must be configured as the playback device in
your application. Please refer to the previous question.
Audio playback sounds really slow or erratic.
The Sample Clock Source selected in the LynxONE Mixer is not connected to an
active clock source. In this case, the sample clock generator on the LynxONE runs
very slow or erratic. This will occur if Digital is selected as the Sample Clock Source
and there is either no connection to the LynxONE’s digital input or the device connected
is turned off. The same situation will occur if either External or Header is the selected
as the clock source and there is no connection to the corresponding inputs on the card.
Audio playback sounds fast or slow when I am using the digital input as
the clock source.
When the digital input is selected as the clock source, the LynxONE’s sample clock
will run at the sample rate of the incoming digital input signal. In the case when the
sample rate of this signal is 48 kHz and a file being played was actually recorded at
44.1 kHz, the audio will playback fast. To solve this problem either change the sample
rate of the device driving the digital input or select Internal as the sample clock source
using the LynxONE mixer.
I cannot change the Sample Clock Source from Digital in the LynxONE
Mixer.
Either the Monitor Source is set to Digital In or an application is actively recording
from the digital input. Under either condition, the LynxONE must synchronize to the
digital input in order to extract data. If the Monitor Source is set to Digital In change it
to Analog In. If an application is recording from the digital input discontinue that
operation first, then change the Clock Source selection.
How do I minimize record monitor latency when I am doing overdubs?
Use the LynxONE’s on-board monitor circuitry. This is controlled by the LynxONE
mixer.
What does the green LED on the LynxONE indicate?
When lit, the LED indicates successful initialization of the LynxONE and the driver.
How do I synchronize my LynxONE with a DPS Perception Video Recorder
card?
Using the Internal Clock Cable available from Lynx, you can connect the PVR’s 27
MHz clock to the LynxONE to maintain perfect A/V sync. Instructions for making this
connection and configuring the sample clock are included with the cable.
