Check System Preferences > Sound > Output or OPTION/Alt click the sound/volume icon in the Menu Bar and tell us, what is listed and checked as Output Device.

Try rebooting if you haven't already. That worked for me after the initial dp5 update

i'm also experiencing this problem, the internal speakers disappeared from output and the mic also disappeared from the inputs. The startup sound works and I can connect my bluetooth speaker. any ideas?

oh dear this is the killer for me too, updated to DP6 and no sound, in the audio prefs initially it works with the internal speaker only, if I select anything else it all goes silent, no headphone out - nish, it's the one thing that means I have to go straight back to Mavericks unfortunately

Look in Macintosh HD >Library>Audio>Plug-ins>HAL

There very well could be outdated drivers in there.


This was a problem when the beta first came out but was fixed by Rogue Amoeba.

i found four folders in >Library>Audio>Plug-ins>HAL

AirPlay.driver\AppleAVBAudio.driver\BluetoothAudioPlugIn.driver\iSightAudio.driver

Are there any missing files ? how can i know if they outdated drivers ?



THANKS

Do you have Airfoil installed? If yes: Delete it.

 

[aiglesia]

No I don't have airfoil installed

Type: ls /Library/Audio/Plug-Ins/HAL

I was looking under user library instead of the os library but still the instanton file is not there just a couple numark and a xone_dx

Another app to check settings in is Midi Settings. I've found sometimes just toggling different settings for the sampling rate can correct bugs with the audio for my USB interface under Yosemite.
