Macbook volume stuck on mute after resetting default keychain?

The Problem: My macbook's audio is fully stuck on mute with no output or input listings.

The Cause (I think...): This issue occurred immediately after I updated my default keychain access. I was not using headphones at the time, and I've never had this issue before. Maybe it's just a coincidence or it's the cause but either way I don't know enough about Macs to be sure. I've also noticed that my mac overheats more often now after the keychain update as well.

System Specs:

Fixes I've Tried:

Restarting, rebooting
Plugging headphones in and out
Cleaning out the headphone jack
Updating
Force quitting coreaudiod
Deleting "com.apple.BezelServices.plist"
Resetting the SMC
Resetting PRAM

None of these options worked even temporarily. The volume just remained compeltely unresponsive.

At this point I'm guessing I'll probably need to take it in, but I figured it was worth a shot.

MacBook Pro (Retina, 13-inch, Mid 2014), OS X El Capitan (10.11.6)

Finally took it in - logic board is failing. Apple employee said that it would also be the cause for my programs unexpectedly quitting. He tried resetting the sound cables and doing a few sound tests, but my macbook kept lagging and wouldn't do the tests.

I didn't hand it in for repair because I can't afford the $475 / 4-5 day repair time (poor college student). Replacing it myself would also cost an arm and a leg, so I'm just holding out until I can afford to repair or just buy a new laptop.

I've heard of the bake method - anyone try this? Not sure if it would fix my issue or work for my macbook model but I'm willing to give it a shot.

Thanks for posting back, but sorry to hear that. Baking, as the link says, is for issues with much older MBPs where solder joints failed. The odds of that being the same thing on your MBP are very slim and could easily lead to other irreparable damage. I wouldn't consider it.

Thanks for posting back! Yeah I was worried about that; it makes sense it wouldn't apply in the same way to newer models. I'll just buy a new laptop when financially possible as mine will be 4 years old in January. Doesn't feel smart to invest $400+ on a laptop that'll probably crap out in another year or two. It's a tool after all - I just wish it would of survived me one more year as I finish my bachelors 😢 In meantime, I'll just backup routinely and edit videos on my college's computers.

Yes, that's where they should be.

What's up with three different versions of After Effects?

I think it's time to bring the Mac to an Apple Store “genius” bar for a free diagnosis: https://support.apple.com/contact

Make sure to backup before going, as you always should.

Hi,

Try this: open Utilities > Audio MIDI Setup > see if input and output show up, and if so > select input and output one at a time and make sure they're not muted and the volume is turned up.

If they don't show up, post back.
