Chosen Solution
Hey, I bought my new Macbook Pro 13" 2020 recently and got it this tuesday. I’ve had this issue a couple of times now with “No output device found” in my sound preferences. So I see this is a general problem and that Apple fixed it in the new 10.15.5 update, but it just didn’t work for me. Still have no audio and it can’t find the output device. I’ve tried everything it seems and read dozens of forum posts about this now. NVRAM, PRAM, SMC, Safe Mode. No CleanMyMac or similar installed and every suggestion on this: https://discussions.apple.com/thread/750… I did a clean install and erased disk, but the problem came again after some time. I’ve tried force quitting coreaudiod in activity monitor, which fixes the problem, but only momentarily. After a restart I have to quit coreaudiod again and I have to manually switch between headphones and the speakers in the Sound Preferences, it can’t automatically. Is this going to be fixed by apple soon? Doesn’t seem like there’s any solutions out there. I should maybe add, that I use Ableton with different plugins, does that cause any problems? Was no problem on my old machine on Mojave. Hope someone can help. It’s really sad to have this many problems from the get go with my new purchase. I’m thinking of returning it, since audio is such a big crucial part of my everyday work, but prefer to solve this.
Your issue is an OS level issue as Catalina (10.15) and how your older apps work with it! Ableton is still using 32 bit drivers which messes up the OS install. Apple no longer supports 32 bit apps or drivers! So when you install Ableton with its 32bit drivers (or other 32bit apps) you are breaking the OS. You’ll need to contact Ableton (and the other apps which have direct drivers) to find out when they will be releasing a full 64bit version of their app and drivers. Nothing here for Apple to fix. Yes, Apple shouldn’t have dropped 32bit services. Two apps I depend on are not being upgraded so I’m stuck too! In my case they are photo knitting apps.
