    @corksta: do you still have the lag of the volume keys? If so, the problem will probably come back. Many people have tried unplugging, waiting, and plugging back in. It usually comes back, even after some days. Please let us know if it continues to not be an issue.

    Has anyone tried this in a Windows environment with either Boot Camp or using the monitor on a Windows PC? It would be easier to diagnose if it also happens on Windows. Won't need an OS patch. Either a firmware for the hardware or an entire replacement.

    No lag with the volume keys at all. I'll post again if it does stop working, and if it stays away.

    In my situation I have a friend with a 2010 MBP so when he brought his over I turned my laptop off and unplugged it, connected his one to see how fast the i5 is to my one, when we finished I connected my laptop back up again and no issues since then.

    at least mac mini users seems to encounter the same issue:

    my display is working kinda fine since i installed the software update, but bizarrely Skype keeps ringing through the MBP - despite adjusting preferences in Skype.

    and me again...
    after one week ACD muted again. SMC reset fixed it.

    This is an unacceptable situation. Apple, fix this!

    OK so that lasted three days - got up this morning and back to the same problem as before, I can't understand why.

    So my understanding is we have three options:

    1. Put up with it and wait for Apple to release a fix.
    2. Never put the computer to sleep.
    3. Buy a 2010 MacBook Pro which supports audio out via the MDP. Seems the 2010 models don't have any issues at all.

    This is ridiculous having to unplug it each time it happens.

    My computer never goes to sleep and I have the same issue. It does look like it's a USB issue. Hopefully it can be fixed via firmware. I haven't heard anything back from Apple. I'm sure they're working on it. Either we need to get new units if it cannot be fixed through a firmware/software upgrade or they will release an update.

    I have had several conversations with a Senior support person over the last couple of weeks. I have been sending log files after each time the sound issues happen. No fix yet.

    Doesn't Apple monitor these forums? Surely someone who can speak to it has seen this or other posts like it. Any response from them?

    I'm having the inability to use the built-in monitor speakers with my 2009 MBP 13". i just applied the 1.0 update for the Cinema Display 27" and now its even worse! The sound lasted about 10 minutes then it cut out right away. Now in preferences I can't even select the monitor as an output, the selection just moves automatically back to the headphone-out jack on the laptop. i'm going to call support tomorrow.
  • theBigD23 Level 1 Level 1 (20 points)
    I've been talking to a Level II tech at Apple, but nothing the last couple of weeks. I'm sure they're working on it and something will happen sometime soon.

    Anyone tried it on Windows yet?

    It also looks like people on newer Macs using MDP for the audio do not have this problem. You do have to plug in the USB for brightness controls and for the USB ports on the back of the monitor. Anyone using MDP for the audio can confirm if you have sound or volume up/down issues when using the MDP audio and also have the USB plugged in?

    I also have the issue - seems to be worse after the display goes to sleep overnight. Nothing I do with the mac pro will bring the audio from the display back, I have to unplug the power to the monitor to get the audio driver to work again.
  • Joshua Peek Level 1 Level 1 (35 points)
    Same issue.

    I'm getting tired of unplugging my display every few days to work around the issue.
  • avidwriter Level 1 Level 1 (0 points)
    i just got off the phone with support and they're telling me they can't send a new monitor to me (mine is only 2 days old) and they expect me to drive at least an hour away to a apple service provider. i'm not about to go driving around the state for a brand new $1000 monitor that should work out of the box. did anyone else get a monitor shipped to them? she said it "wasn't even an option" for her to do with a Cinema display. that doesn't sound quite right.

    They offered the option of display replacing via mail to me, but I was supposed to send it first and it was just easier to drive to the Apple store and get the replacement immediately.

    The bad thing that new one still has the same problem and it does not seem like just my bad luck - there are few people on this thread who have this issue after replacing it.
  • theBigD23 Level 1 Level 1 (20 points)
    I've also been offered to have my monitor replaced by mail. However, there is zero point to doing this. You will just get another monitor with the same problem. From what I've been reading, every person that has one (or more) replaced, has the same issue. Either a firmware will be released or they will fix it at the hardware level. It is then safe to replace it. Don't waste your time replacing a monitor. You'll have the same issue.
