macOS Sierra - No Sound
I just updated to macOS Sierra. Now I have no sound what-so-ever.
Checked all the usual things (speakers, volume, settings, etc.).
Is there a macOS 10.12 sound driver or anything that I can reinstall?

It's sadly true, widely documented on Apple Communities and Apple Developer Forum on Apple Seed official website.
You need to double check to reliable sources as I did, as simple denial is not very helpful here, pushing people losing their
time with reboot, changing cables and whatnot.
It's also officially announced on Fostex and Chord website.

As per NDA Agreement, I cannot link here to internal Apple Seed, but I can assure you several of us have filed a thread there on that very issue.
Reinstalling OSX seems to be little bit harsh before trying other steps.
Restart laptop and when system starts hold down CMD + ALT + P + R
Hold it until screen flashes 3 times and then let go off the keys.
Step 2 fixed it for me.
I've done everything short of reinstalling OS. So I'm "relieved" to hear Hellstan's comments. It shows that experts are just as baffled as I, a non-technical user. Yesterday my iMac got an SSD installed along with Sierra. I had been using 10.9.5 so, unlike most others on these threads, I couldn't assume the trouble lay with Sierra. Now I can.
On the bright side, I use a Tascam USB interface (US-100, discontinued but faithful), which still gives good input and output. Also, I DO have internal speaker output from system alerts and Audacity. Curious.

Kappy,
Your solution fixed my Mac Mini. In my living room I have a Mac Mini for the sole purpose of playing music from iTunes. After installing Sierra, ALL audio from ANY source went dead. After reinstalling Sierra using your procedure the headphone jack is working again.
Thanks for all you do.
SON OF A GUN !!! I've been fighting this for months on an i5 Intel Mini that lost audio after 10.12.3 and just found your post tonight after 5 hrs of searching and trying dozens of fixes. This worked perfectly !!!! lukefrombrno - You're the bomb !! I owe you a few rounds at the pub my friend.
THERE YOU GO APPLE - NOW YOU KNOW WE AREN'T CRAZY - SO PLEASE HUNT IT DOWN AND FIX IT !!!
I had the problem, but it is solved now.
Before I tell you what worked, you should know I tried everything on support community sites, and via Apple, reinstalled the upgrade to Sierra, to no avail. Apple advised me that the only solution left was to wipe the entire computer clean and reinstall the operating system, and that might not work either. Initially, they said it must be a hardware issue. I did not want to potentially lose data, programs, etc., so I passed.
A headset worked, so I went out and got a cheap external speaker at Goodwill. I plugged it in, and WOW. Instantly, the internal speakers reappeared in sound preferences, with volume controls and everything. The internal speakers work perfectly. The external speaker did not. Unplugged the external speaker and all internal speakers functions remained intact.
Hope this helps somebody.
Hallooo my friend I had the same issue..but after days and hours searching to resolve finally I found the solution I hope this will help u check the link and follow the instruction
You can always try a restart of the computer, to sort various glitches.
Yep, tried that, as well as running Disk Utility. Still no love.
Reinstall Sierra:
Reinstall OS X Without Erasing Drive
Please be sure you back up.
- Restart the computer. Immediately after the chime hold down the Command and R keys until the Utility Menu appears.
- Select Disk Utility and click on the Continue button.
- Select the indented (usually, Macintosh HD) volume entry from the the side list.
- Click on the First Aid icon in the toolbar. Wait until the Done button activates, then click on it.
- Quit Disk Utility and return to the Utility Menu.
- Select Reinstall OS X and click on the Continue button.
Also, see this User Tip: Basic Steps for Upgrading OS X.
Thanks Kappy, I will give that a try.
I have booted into a 10.11 backup and the sound is working, so that confirms that it's a 10.12 issue and not speakers or anything else.
Re-installing now...
Thanks guys. When I booted back into 10.12 from the 10.11 backup, the sound mysteriously came back.
Appreciate everyone trying to help 🙂
I find that sound is often muted for me. Even in Apple Mail, I have to first select to play a sound in a rule, THEN the sounds works. Somethings strange in the neighborhood....😝
