No sound device detected after installing Mavericks!

[shlores]

Hi, friends!

I'm suffering some strange issues after installing Mavericks on my 2009 iMac 27". Everything seemed fine when updating it to DP5 (fresh DP1 install and then updates to DP5), but when I tried to play some iTunes music, I realized there's no sound on my computer. I've checked Sound on Control Panel, and there's no audio device detected (input nor output).

I've done the same process on my MacBook, but it's suffering the same issues: no sound device detected. I've also tried to fix HD permissions, deleted com.apple.BezelServices.plist (i read it on Apple Support Page) and reset PRAM, but there's no fix to my problem.

What can I do? Is there any related bug? Anyone has the same problem?

Thanks in advance!

I don't have any solutions, just wanted to note that I'm now on DP7 and still having the same issue - no sound, no sound output detected in System Preferences whether I have speakers plugged in or not.

Well, on my rMBP...
I settled it by copying the ML kext for audio over...

Now I have the issue where System Preferences crashes when trying to get into Displays with a second screen plugged in.... :/

Same issue with rMBP. And my display panel of system preference also crash.

Same issue with rMBP. And my display panel of system preference also crash.

I have exactly the same, Sound not working and also Display Panel freezes when opened.

Apart from that, I'm liking Mavericks
