Cinema Displays dropping audio, show slow volume control

updated 12:30 pm EST, Wed December 1, 2010

Problems uniform between Mac, Windows

The 27-inch Cinema Display is suffering from serious audio problems, some owners say. AppleInsider notes that complaints first began in October, but have persisted without any solution from Apple. In worst-case scenarios Cinema Displays have been losing built-in audio entirely, although the glitch can be temporarily solved by unplugging and reconnecting the monitor, or in some instances changing audio settings.

Another problem involves slow response times for keyboard-based volume controls. Affected displays can potentially take as long as 6 or 7 seconds to respond to keyboard presses, making onboard sound impractical.

Issues are notably affecting both Mac and Windows systems, suggesting that any permanent solution will require a firmware or hardware fix. The root cause may in fact involve USB connections, as Macs using Mini DisplayPort for audio have been going unaffected. Apple support staff are said to be aware of the problem, but unable to tell if or when a fix is coming. Some customers have managed to secure replacement monitors only to encounter the same trouble.

    My 24" CD had this issue too with my 2009 MBP

    But when I got my 2010 it vanished.

    Its not just the audio output

    first of all, thanks for the write up.

    the issues also include (in the affected displays) loss of mic and sometimes the camera. the problem increases over time, becoming more and more frequent.

    but...

    Apple support staff are said to be aware of the problem,

    Does that mean someone told Apple support this, so they must be aware?

    Or someone at Apple support actually said the phrase "Yes, we're aware of the issue"?
