Sound defaulting to JumpAudio

[mk313]

Hoping someone here can help. I used to use Jump Desktop & had it installed on my Mabook 12", but since work from home, I no longer had the need & removed it (I got it from the App Store, so I removed it by going to the Launchpad & deleting it there).

Now, two years or so later, I restart my Mac & there is no sound. I go to the Speaker icon in the menu bar & it shows the output is defaulting to Jump Desktop Audio, and my internal speakers & the headphone jack are both missing as options, although I do see options for Airplay Devices in the house (Apple TV's, etc)

When I do an activity Monitor search, I see that something called Core Audio Driver (JumpAudio.driver) is running, but when I do a system search for that, I don't see it anywhere on my computer.

Not sure how to get rid of that & get my internal speakers working again.

I've no experience with Jump Desktop but I would not think it should remove the other audio devices from the menu even if it adds a new one. Are they visible within the Audio MIDI Setup program?

Could you run the Terminal command
kmutil showloaded
and see if the mentioned driver appears as a loaded kernel module? If so, try using kmutil unload with its identifier on the listing
I would look for it under /Library/StagedDriverExtensions and /Library/StagedExtensions

Thanks for the reply. To answer the questions:

1. The built in speakers & audio jack are NOT visible within the Audio MIDI setup program
2. I ran the terminal command you showed & the JumpAudio.driver does not show up in the list.
3. I went into my Library folder, but I don't see anything called StagedDriverExtensions or StagedExtensions. The only thing similar I see is Staging, but that folder is empty.

I also tried to add an external speaker & it shows up on my list of bluetooth devices, and shows that it is connected, but it doesn't show up in the list of sound options.

When I run a system report, the only Audio devices that show up are Jump Desktop & my iPhone.

Thanks again for the help. Not sure what actually happened, but I tried Disk Repair & got some error that the repair couldn't be completed, so I'm not sure what it's called, but I restated while holding down the D key & it went into some kind of internet recovery startup. It didn't appear to find any issues, but when I restarted after that, my speakers were visible & working again. So while I have no idea what caused it, at least this has now been resolved.
