Check Clock Source and Sample Rate Configuration
Check the clock source and sample rate configuration of Symphony I/O as described in the KnowledgeBase article below. Carefully verify the Enable Sync to External box as described in the document; if clock source is Dante Network, the box should be unchecked; if clock source is Internal or any external source, the box should be checked.
Check Your Network Switch
- Check that all Ethernet cables are firmly connected at both the Symphony I/O and network switch ends.
- Make sure you're not using an "Energy Efficient Ethernet" (EEE) or "Green" switch. If your switch does include these features, consult the switch documentation to determine if they may be disabled.
Reset Symphony I/O
Reset Symphony I/O by pushing and holding the front panel power button for at least 10 seconds, then powering the unit back on.
