Sound stopped working

[marcostulio]

Once installed DP7, my sound no longer works.

Can someone help me? 😱

First, I would report the issue to Apple (meaning, get the system diagnosis before trying to fix the issue).

Not sure if this will fix it but try running this inside Terminal (/Applications/Utilities/Terminal.app) to restart Core Audio:

sudo killall coreaudiod
