Upgraded my Mac Mini this morning with latest update. Ever since, everytime I switch source on my TV from one to another, I'm not garanteed to have sound being output on my Mac Mini. Only solution is to reboot.

 

Am I the only one facing this kind of issue???

    You might try this:

     

    Repair the Hard Drive and Permissions - Lion/Mountain Lion

     

    Boot to the Recovery HD:

     

    Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.

     

    Repair

     

    When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list.  In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive.  If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported then click on the Repair Permissions button. When the process is completed, then quit DU and return to the main menu. Select Restart from the Apple menu.

     

     

    Then download and install: OS X Mountain Lion Update v10.8.5 (Combo).

    Hi,

     

    Thanks for you quick answer but would that help? Can you explaint to me? Thank you! That is if I install again OSX 10.8.5

    Yes, it may help. The idea is to first fix any hard drive and/or permissions issues that could adversely affect the system. Reinstalling the update using the Combo updater often helps fix old update problems as well as possibly fixing something that did not install properly with the incremental updater.

     

    No harm will come to the computer. If it helps then your problem is solved. If not, then you have to look elsewhere for a solution.

    Tried this. Event went as far as reinstalling my OS. Same problem. Looks like Apple broke something related to HDMI or sound or whatever. Sigh...

    I have no sound after updating to 10.8.5. I have to restart or pull the HDMI cable out and plug it back in. This is incredibly stupid and Apple needs to fix this asap. I cannot restart my computer each time if I want sound.

     

    Running a MBP 13 2011. No sound issues beofre this update, if you guys keep this up, I will avoid any updates, since you're obviously not checking them before release.

    Behavior is sporadic. After having reinstalled my Mac, I don't systematically have it as I used to have when I started this post. It also seems that it depends on the version of the app I'm using (Plex)

     

    But I agree, this is really bad... Hope they'll fix it soon enough.

    Youtube, iTunes, Safari, nothing, no sound after waking from sleep. I just reinstalled the OS using the combo updater and same issues.

     

    I am not using any other sound app. Just my basic sound functionality is missing after sleeping. This is just absurd that Apple would let something like this go. I've been a huge Apple fan and am now starting to lose respect for the sloppy updates like this.

     

    This is just absurd.

    Now videos will not play if they are paused. Youtube, iTunes, etc. If I start any media, then pause, it will not play again - frozen. ***?

    Same problem with me. Updated to 10.8.5 on my Mac Mini and no initial sound output. I get sound back by going into System Preferences > Sound > Selecting the sound output device by highlighting it and then clicking on the volume control which then outputs the blip noise telling me I have sound again.

     

    Apple need to fix this issue as I don't want to go through this everytime I boot up.

    Ive had no problemes with my 2012 Mac Mini Until this 10.8.5 update. After the mac wakes from sleep HDMI sound does not work. I need to restart the mini to get HDMI sound working. Its not the HDMI cable since it works with other devices. Sound does not work with any program that plays sound. Come on Apple this is sloppy

    I am having the same issue on my 2012 Mac Mini. I usually have no sound after my computer comes back from sleep. I can get the sound back by restarting my computer. I hope Apple fixes this issue soon.

    Hi Kappy,

    I'm just curious.  How is running Disk Utility from the Recovery HD different from running DU after you've just restarted normally?  Is there something different after everything loads?  I've run DU sometimes after having restart problems and spinning beach balls, but I always just ran it from the Applications folder after the Mac started.  I've never found a serious problem; but running DU as you described usually repairs some permissions, and things just seem better afterward.

    Thanks,

    Richard

    I have had the same issue on my 2012 MacBook Air. Every time I wake my computer up from sleeping, the HDMI sound is just GONE. I have to restart my computer to get the sound back again.

    I have contacted Apple Care support and they just asked me to reset SMC, but I did not work.

    It seems that my computer's problem is not the only one. I hope Apple fixes this issue soon, too.

    You cannot repair the startup disk, so you must boot from a different disk then use Disk Utility to repair the main drive.

     

    Disk Utility can repair permissions without booting from the Recovery  HD, but it cannot repair the hard drive.
