Loss of sound after waking up from sleep

I am currently using OS X 10.8.5 (12F37).  After upgrading iTunes to 11.1 (126)  I lose sound after the computer wakes up from sleep.  This was not a problem prior to the iTunes upgrade.  The only way to correct the problem is to restart or shut down then restart the computer.  Are there any other solutions to this event? 

This is not just a Mac Mini problem.  I've found comments from people with all kinds of Mac, with any kind of external sound device, who all have this same issue.
The common factor is Mountain Lion.
Apparently there is a new build (12F42) which is supposed to fix this.
http://www.gadgetguide4u.com/new-os-x-1085-build-number-12f42.html
Apple released it to their employees on the 25th Sept.
Yet they don't even seem to have told their support people about it.  My local apple store replaced my Mac Mini just on Sunday, because they didn't know why it was behaving like that.  Needless to say, the new one has the same problem.
Here's hoping that build is available soon ...

  • Strange, Frequent electronic sounds after waking iMac from sleep.

    Since i began syncing my iPhone (8GB) V.1.0.2 to my 20" 2.4Ghz iMac, a strange electronic, interference sound come from the computer immediately after I wake it from sleep.
    The sound starts as the Comp awakens and continues off and on frequently for about 5-10 minutes. After that times passes, the strange sound ceases temporarily. Once 10 minutes have passed the time interval between the electrical interference sound is 10 minutes or so. I have the same desktop speakers plugged into the audio out jack that I have for a month now.
    The odd thing is I can MUTE the sounds from the keyboard button and the sound continues regardless. I believe the sound is coming from the built in speakers rather than the external speakers.
    Also, this problem crept up before the iMac update today.
    I tried searching the forums here but I didn't turn anything up. can anyone suggest a solution?

    I just noticed that the closer my iPhone is to the speakers in my Intel iMac or my home theaters speakers causes a frequent audible interference. Is this a known issue with AT&T's GSM or is it something unique to the iPhone?

  • Hello, I have a macbook pro late 2011 15 inch with 4 gb ram. My macbook runs extremely slow when logging in after waking up from sleep, locking up and I am unable to use the keyboard. Is there a fix?

    My macbook runs extremely slow when logging in after waking up from sleep, locking up and I am unable to use the keyboard. Furthermore, when just using safari to watch streaming television, my computer gets really slow, and locks up, and the dock appears blank and I sit here frustrated. Anytime i wake up my computer, my keys don't respond and I've waited at most 3 minutes untill i can type in my password. Even sometimes when i type in my password and hit enter, it takes forever to open up my mac. I have barely used any storage in my macbook, since i only use it for college, and I have run clamscan wiht no viruses showing... Any ideas?

    Please read this whole message before doing anything.
    This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
    The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device. 
    Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
    Safe mode is much slower to boot and run than normal, and some things won’t work at all, including sound output andWi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
    The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

  • Ethernet interface disappears after waking up from sleep

    Hi guys,
    I've been trying to debug a networking problem without any luck and I think it's about time I ask the forum for help.
    My ethernet interface no longer works after I wake up my computer from sleep. I have no idea why.
    Before sleep:
    # ls /sys/class/net
    lo wlp2s0 enp3s0f2
    After waking up from sleep,
    ls /sys/class/net
    lo wlp2s0
    Here are the list of services I have running.

    Furthermore, plugging in the ethernet cord after the computer has started doesn't connect to the internet, even when I have the ifplugd service running. I am forced to run:
    sudo ip link set enp3s0f2 up
    sudo dhcpcd enp3s0f2
    However, I can't run these commands after the laptop wakes up from sleep since it no longer sees the ethernet interface.
    I am thoroughly confused. Please help me.

    It seems to be fixed after the kernel update. On an related note, I've switched from using dhcpcd to netctl. I've enabled netctl to automatically connect to the network using:
    # systemctl enable [email protected]
    # systemctl enable [email protected]
    So when I check for the status of the ethernet profile, I get told that's it's inactive.
    #netctl status ethernet-dhcp
    netctl@ethernet\x2ddhcp.service - Networking for netctl profile ethernet-dhcp
    Loaded: loaded (/usr/lib/systemd/system/[email protected]; static)
    Active: inactive (dead)
    Docs: man:netctl.profile(5)
    But I turned off the wireless, so I must be connected to the ethernet, So how do I know which profile I'm connected to?

  • W510 eSATA/USB2.0 combo port does not respond after waking up from sleep mode

    Has anyone tried to connect external DVD/CD player or burner to the eSATA/USB combo port and experienced very slow system performance after waking up from sleep mode?  It might takes minutes to launch an application program that usually takes just few seconds.  My W510 can not even restart.  It will just stop at the Thinkpad logo if I tried to restart after waking up from sleep.
    The funny thing is if I moved the external DVD/CD player to the USB2.0 port in the back, everything went back to normal.  I don't know if this has anything to do with the fact that the combo port has something to do with eSATA.
    Thanks

    It seems that this problem is unique to my system. I am hoping that one of the Mac Guru's will have at least a pointer in the right direction.
    Thanks.

    Why does my Mac screen suddenly go dark? Sometimes it stays dark for an indefinite period after waking up from sleep. I have to open and shut the monitor screen to get it to light up again.

  • Lose connection to external USB hard drive after waking up from sleep

    My Mac lost connection to the external USB hard drive after waking up from sleep. I can still see the folders in the hard drive in Finders, but when I double clip a folder no file within the folder is displayed. I have to reconnect the hard drive with iMac to read its contents.
    May I ask how this happens and is there a solution?
    I'm using Paragon NTFS for Mac OS X to read from and write to NTFS format of USB external hard drive.
    Thanks!

    ... I un-ticked the "put hard disks to sleep when possible" option in the Energy Saver panel in the System Preferences, and it seems the problem is solved. will have to sleep and wake up my iMac to further verify if this is the solution ...
    Alternative advices are always greatly appreciated!

  • Compaq C700 - CPU fan not running after waking up from Sleep mode

    Hi guys,
    Waking up from Sleep mode does not start the CPU fan.
    Kernel:  2.6.32-ARCH
    KDE : 4.4
    Let me know what other details you need.

    I was having the same problem after installing mountain lion.
    What i did was in Finder went to /Library/Preferences/SystemConfiguration/  and deleted all the networking plists (refer screen shot). Then restarted the Mac and in Network Preferences reconnected to my WLAN.
    That solved the problem.

    Hi,
    I have almost the same problem with my T540p, except that there is no internet connection not only after waking up from the sleep mode, but also when starting windows and sometimes the internet connection will get suddenly lost during normal windows run.
    I tried installing all kinds of drivers - latest from intel, latest from lenovo update (which is always different version from the one from intel), some older versions. Nothing helps.
    Re-enabling the WiFi device like Aaziz1982 suggested, doesn't help.
    Here is a more detailed description of my problem: http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/T540p-WiFi-Connected-no-internet/m-p/177818...

  • Satellite P200D-11R sound and graphics crash after waking up from sleep mode

    Hi,
    I am wondering if anyone here has had similar experiences to mine (below) or can offer any solutions.
    I have upgraded my P200D-11R OS to Vista 64 Ultimate to take advantage of the extra performance. I also add that the BIOS has already been updated to version 1.4.
    Well, everything works fine with the standard 2Gig of RAM which the laptop was supplied with originally, however, when I upgrade the RAM to 4Gig (2 x 2GB Samsung 667mHz modules), sound and graphics problems appear every time the machine is brought back from sleep mode.
    The sound card makes a very laud fuzzy noise every time it wants to play a sound and the graphics produce lots of horizontal lines on the screen. I then just have to restart the machine which means loosing all my unsaved work.
    Everything works fine as long as the machine does not enter sleep mode. I have currently disabled the sleep mode to prevent the machine from entering it but I am finding life very hard without it.
    I am very surprised and also disappointed at the fact that Toshiba did not test these machines with Vista 64 Ultimate and 4Gig of RAM!
    Extra info:
    The memory is the same Samsung type as the 1Gig modules supplied by Toshiba originally with the machine, and the part number Toshiba recommends.
    I have tried installing other (more recent) device drivers by Realtek and ATI without any improvements.
    The memory modules pass all tests and are not defective. They have also been tested on my friends Dell notebook with no problems even in sleep mode.
    I have installed my friends Dell 2Gig memory modules in my P200D and they too produce exactly the same results with post-sleep crashes.
    My thoughts are that this must be another BIOS issue unless anyone can shed some light on the issue from another angle.
    Please help! Many thanks in advance.

    Hi Sascha
    Since you are running a Vista 32bit version, the upper limit of the memory recocnised by the machine is 3.2gb which is the maximum a 32bit operating system can address and use. The diffrence here is that I also upgraded my OS to Vista Ultimate 64bit to get yet better performance out of the 64bit dual AMD processor.
    3.2gb of RAM on 32bit OS does not necessarily increase the performance. However, it keeps the performance stable when you open many more programs at the same time since the machine has more RAM to play with before staring to use the much slower hard drive as operating memory (Page File), to keep all thoes open programs running.
    A 64bit OS such as Vista Ultimate 64, recognises the whole 4gb of RAM and much more (for instance, 8gb with 2 x 4gb RAM modules). The 64bit OS itself would generally consume more RAM to start with, however, with 4gb I found the general performance to be much better. Going back to the problem however, my P200D-11R with Ultimate 64 and 4gb RAM refuses to wake up from sleep mode gracefully and the graphics and sound crash every time, forcing me to restart.
    My feelings at present is that eventhough your machine may be slightly different, I bet if you upgrade your OS to 64bit, the machine will start recognising all of the 4gb of RAM and post-sleep crashes will start to appear!

  • Hi, Lately many times my MBP15 shuts down a few second after waking up from sleep mode. Any ideas why? I think it happens everytime I try to open safari right away...

    I think it happens everytime I try to open safari right away, but I'm not sure. After shutting down it automatically restarts and gives me a message Ÿour computer had to shut down because of a problem, press any key to restart..." and when it comes on again it gives me an option to send an error report to apple.
    Any ideas?
    Thanks

    Yeah your Mac is having a Kernel Panic and the option to Restart the system when that happens is checked. So the system Restarts Automatically. Uncheck that option. For some unknown reason it is located in the Energy Saver applet in System Preferences.
    As to the ROOT cause it could be software or hardware problems. There should be a Kernel Panic report in the console logs.
    But if you do a search of these forum you'll find many that are having these restarts waking from sleep. So it would seem to be a hardware problem.

  • After waking rMBP from sleep and typing password, rMBP goes back to sleep after a few seconds and won't wake for about 7-8 seconds.

    Absolutely embarrassing. What is going on here? When will we see a fix?

    This happens rarely but consistently! I't seems to happen about 5% of the time waking from sleep. It MAY be more prone to happen if I had been moving with it in my bag, but it can happen at any waking time after any duration of sleep.

  • Dead USB controller after waking up from sleep

    Hi,
    I posted this a while back but the issue is still unresolved. I am experiencing USB port sleep issues after upgrading to Tiger (currently running 10.4.8). Sometimes the build-in USB port that has my keyboard connected to literally wakes up dead from sleep. Here is the error message from the Console log
    (XX-Computer kernel[0]: USBF: 24445.528 AppleUSBOHCI[0x15ab800] Watchdog detected dead controller (hcca #: 56759, hc #: 64465).
    This happens with no set pattern, sometimes it wakes up fine, other times the port is dead. A restart is required to bring it back to life.
    Any ideas why this is happening? If I plug in my keyboard to the other USB 1.1 port everything works fine (the port remains dead until the next restart). I also have a USB2 PCI card that works with the keyboard without any dead port issues but I can't use it for waking the computer (does not trigger wake up), but I simply prefer to use one of the equipped USB ports for my keyboard.
    I have 2 external FireWire HD's connected at times, one daisy-chained to an external FireWire CD Burner. I have a USB 1.1 hub connected to the other equipped USB 1.1 port, and a USB 2 PCI card installed.
    I run system maintenance tasks frequently (Onyx) and repair permissions prior and post SW installs and updates.
    Thanks for any input.

    It seems that this problem is unique to my system. I am hoping that one of the Mac Guru's will have at least a pointer in the right direction.
    Thanks.

  • Slight crackle coming out of the speakers after waking up from sleep?

    anyone else had this happen to them? I just hear a short, quiet crackling noise coming out of my speakers after waking up. My MBP 17 is great otherwise. Its not really even a big deal, just wondering. Thanks

    I've been encountering this problem recently with my left speaker when waking my laptop from sleep. It doesn't happen all the time though - almost seems like it happens when it's hot and humid out, like today, even though my A/C is on. I've seen one or two more threads about this topic but with no real help other than "I wouldn't worry about it". Does anyone else have any ideas? It's not a life-or-death ordeal, but still, I know the speaker shouldn't make this noise.
