    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    There very well could be outdated drivers in there.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.

    How to update them ?

    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 how can i know if they outdated drivers ?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.

    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.
