Apollo sound card not recognized because of Ventura update

I had the same issue and had long conversations with UA tech support, but they couldn't find any problem on their side. Today I spoke to Apple support and they found a solution for me: resetting the SMC. So I unplugged my iMac M1 for 15 seconds, then connected it again and when it started up Apollo Solo was working just as it should. I hope it works for you guys too.

After a couple of weeks, I got my Solo back from the Repair Center. Its DSP just died. It wasn't actually a software / firmware issue. The technician said he's getting an expressive amount of complaints regarding the Arrow or Solo units for the last year or so. It seems the chip is failing for an unknown reason. Really didn't expect that to happen on an UAD device.

Hey guys, this one solved it for me:

Did it! Deleted the UAD folder as well as the com.uad files as mentioned on their website.

I am having the same issue. Last night my Apollo Solo was working. This morning after the Ventura 13.3.1 update Mac M1 the sound card disappeared. My next step beside the classic unplug and plug, shut down and restart, was to install the latest Apollo Solo update, but in vain.

Since when did Mac turned to be a hassle like Windows?

This is absolutely unbelievable. I was on Mac OS 11 and Apollo was working fine.

I updated to Mac OS 12 and the latest UAD 10.2.5, and no matter what I did (unplugging, hardware resets, uninstalling and reinstalling), Apple Music WILL NOT PLAY through my Apollo. This is a 4 thousand dollar MacBook and a 3 thousand dollar interface that CAN'T PLAY MUSIC. WTF???

I then updated my Mac to OS 13.6.1 and uninstalled and reinstalled UAD again. Unplugged the Apollo again.

All procedures have been followed. WTF is going on with this? It's absolutely driving me nuts.

Having the same issue here. Apollo Solo suddenly stopped working after 13.3.1 (a). I can still see it on System Information as a connected Thunderbolt device, but not happening anything else.

The manufacturer likely needs to update their firmware or driver/software.

Hi Marc!

Yeah, did that but still nothing happens. My Apollo is literally not turning on, although on System Information it's shown and detected on my Thunderbolt/USB4 port as a "Device connected".
