Question: MAC OSX Sierra Internal Speakers Missing
I just last night, installed the new SIERRA OS on my MACBOOK PRO. I am having an issue with sound across my Internal Speakers. I get sound over my headphones, but in the SOUND PREFERENCE, there is no INTERNAL SPEAKERS for OUTPUT. I have been doing a bit of research and keep coming across the COREAUDIOD.PLIST I have tried the Terminal KILLALL commenad but, it says it is not even loaded. I attemepted a LAUNCH and is says it does not even exist. I a search in the LAUNCHERDAEMON folder and there is only 1 file in that folder and it is NOT COREAUDIOD.
Can anybody help resolve this issue for me? It seems to be a fairly common issue. ALSO< I do get the startup CHIMES so, I know the Internal Speakers do function.
MacBook Pro, macOS Sierra (10.12.2)
