Q:
828 Firewire audio interface Optical LED activity on 828 even when the optical bank is not configured
 
A:
Optical LED output activity may be visible on the 828 even when the optical bank is not configured, and there is no optical signal. This is a known symptom of the version 1.0 828 Mac driver and enabler. MOTU has updated the Mac driver and enabler to correct this.
Update 828 Driver and Enabler is available on the MOTU Website.
