10 Troubleshooting
Clicking, popping or crackling noises in your audio:
1. Check clock master settings. In any digital audio configuration, there can be one, and only one master clock. All
other digital audio devices must be configured as slaves to the designated master clock. Since the AES16’s
SynchroLock
™ technology provides an extremely stable and jitter-resistant clock, we recommend setting the AES16
as the master clock in your digital audio system.
2. Check buffer settings in your audio application software. Smaller buffer sizes are preferred because they reduce
latency (the time it takes for an audio signal to travel through your audio software). In some cases, however, setting
too small a buffer size can overtax your computer’s processor, particularly when running multiple tracks and/or a
number of DSP plug-ins. This can result in clicks and pops in your audio playback. Try increasing the buffer size
and see if your playback performance improves.
Audio plays back at a faster or slower rate than expected:
This is usually the result of mismatched clock rates and multiple clock masters. For example, if you are playing back
a file recorded at 44.1 kHz, but you have set the clock for 48 kHz, the file will play back faster and at a higher pitch
than expected. Make certain you have set only one device as clock master.
No audio:
If you see signal appearing on the AES16’s output meters, verify your output connections, making certain you have
a valid signal flow from the AES16’s outputs to your mixer or other D/A device, and from that device to your
speakers.
If you see no signal appearing on the AES16’s input meters, verify your connections, making certain you have valid
signal flow from your digital audio source to the AES16’s inputs.
