OSX 10.8.5 Update HDMI sound not output after source switch

in the same boat here. Did leave feedback. hope apple does something soon because this is ridiculous!

Same problem. Mac mini. I've had no issues until this latest update. Now I lose sound every time it comes back from Sleep mode. Only a restart restores it for that session.

Great thread - thanks for the temporary fix (repairing disk then restarting) however, as everyone else has found this only works once as you have to then restart each time to get sound working rather than just waking from sleep mode. Its a very annoying bug and Im seeing this on a Macbook air. Have left the feedback for Apple too (thx for that link as well!), lets hope they fix very soon.

I'm surprised there's still no fix for this.

Same issue with late 2012 quad-core.

No! You are not alone, this same exact issue as you describe it perfectly is happening to me.

At first I thought the hardware was failing, but now that I read your issue I know that it is the recent spate of "updates" that Apple pushed out.

Clearly they have broken something in the code...

Lets hope they fix it ASAP, I am very disappointed!

How do we "file a report" ??

How about a link next time?

It's been posted several times in this topic already, but one more time: http://www.apple.com/feedback/macosx.html

Also, please note that many users are not seeing this behavior so it is possible the cause is something other than the update itself, even if began immediately after the update was applied. It may not be true for this particular problem but it is quite possible some third party system-level addition is interfering with normal operation (or interfered with applying the update properly).

For this reason, you need to include in your feedback report any info you can about this kind of software that might have been installed & running on your Mac when you applied the update. One way to gather that kind of info is with Etrecheck, a free little utility written by a forum regular. It is intended to be used to post this info to these forums (& it isn't a bad idea to do that) but if you know something about daemons, agents, startup items, etc., you can copy the relevant info to your report.

It is important to do this because Apple can't fix something it can't reproduce during testing, & it probably won't fix anything that isn't caused by its own code.

I posted previously about having the same issue. R C-R made the comment about not all folks not having the same issue and I got to wondering if there is anything similar in our setups. There seem to be a number (but not all) that are using Mac Minis connected via HDMI to a TV and utlizing the device as an HTPC.

I'm wondering how many have installed some alternate audio codec. I've installed Perian and am going to uninstall to see if it makes a difference. If it doesn't, I'm going to reinstall the last patch as well to see if that makes a difference. Other than that, my Mac is pretty basic vanilla deployment.

Repaired permissions did nothing. I used to have Perian installed - but uninstalled it some time ago.

Interesting.

same issue, very annoying

The only temporary fix i have found so far is to reboot my macbook air, go to system prefs and turn off sleep. As long as the laptop never sleeps then the sound stays on......

Did you ever try starting up in safe mode to see if your problem disappeared? It doesn't take long & it will tell you very quickly if the cause of the problem is in the OS itself or something else.

You also might want to run Etrecheck & post the results. It isn't that unusual for some app to install a system level component, often without any explicit notification to the user that it has done so. If that component is not fully compatible with an OS update, it can cause all kinds of weird issues, including with things not directly related to its function.

run Etrecheck & post the results.

So, I uninstaled Perian, but no change. I have yet to attempt to re-run the update. I did do an Etrecheck. my results are:

I see some fails in there. I could probably uninstall LogMeIn and the Wacom tablet. Neither are really being used on this machine. The only other thing that I wonder about is the "Problem System Launch Agents" section. Without looking, I don't know if that is normal or not.

Thanks in advance for looking.

Here's mine. See anything noteworthy? I don't, but I don't exactly know what I'm looking for, either.

Some have mentioned that a re-install of the 10.8.5 combined update fixed the problem:

http://support.apple.com/kb/DL1676

https://discussions.apple.com/thread/5316801?answerId=23139146022#23139146022

How do you go about a re-install with the combo update if already updated to 10.8.5?
