Only for the 27-inch LED-backlit model
Today Apple issued a firmware update for the 27-inch LED Cinema Display (the model introduced on July 27th) which addresses intermittent audio dropouts some users have experienced while using the display, which had been previously addressed in a technote on Apple's support site. Under certain cirumstances, audio would cut out, and require unplugging the display or restarting the computer. This is not the same update as the LED Cinema Display Software Update 1.0, issued this past September.
The updater will be installed in the Utilities folder and will launch automatically. Users should follow on-screen instructions to complete the update. This update requires a 27-inch LED Cinema Display, and 10.6.4 users should ensure the earlier software update v1 linked above has already been installed. The update was included in 10.6.5, so those users can proceed without the earlier update.
