Hi - I need to set a short delay for Jack auto-start to allow the usb audio interface to register first. I have set the auto-start Jack at login option in Cadence. The latest O/P from Jackdbus.log is below which shows the error when auto-starting and then the correct manual start after a short delay.
Thanks for any advice.
