Installed both the first and second updates of Highe Sierra. Since then, my sound doesnt work on the computer. I could play music from Mac to my external Bose wifi but no sound plays on the Mac. The starting chimes works perfectly but after the OSX is up, the sound symbol appears up right and greyed out. When I click on the preferences, it takes time to load and then encounters problem and there is no input, output and source.
I have tried both the PRAM and NVRAM and SEC twice to no success.
How do I go about resolving this issue. Yes this is Beta but this is weird.
Thanks
