ASI5111/5211 Auto Clock switching issue 2015-23-14|
Some ASI5111 and ASI5211 cards may exhibit an issue whereby the AES/EBU input appears to have a valid input when none is actually present. Because, by default, the card will automatically switch to the sample clock generated by the AES/EBU input, this will cause erroneous clocking and garbled audio.
We thereby recommend that you turn off the automatic clock switching feature of the ASI5111/5211. To do this run ASIControl and select the ClockSourceIn 1 node of the ASI5111/5211. Un-check the “Auto Clock Switching” checkbox. Then change the “Clock Source” to “Local”, if it is not already set to “Local”
Note: To use the AES/EBU input as a source of audio in the future, you will need to manually set the Clock Source” to “AES/EBU Sync” before attempting any recording.
