I have asked this question elsewhere without success but now I have found this forum I’m hopeful!
I and running 11.2.1 Big Sur on a 2017 Macbook Pro with 16gb of RAM. I use Logic Pro as my main DAW and Audacity as my audio editor. I have relied on Audacity for many years for any audio work even before I used logic. A few months ago I started getting 2 errors on recording and playback.
I have deleted Audacity, including the library files, and reinstalled no change.
I have reset Audacity manually deleting audacity.cfg, pluginregistry.cfg and pluginsettings.cfg.
I have used Tools/ Reset Configuration.
My Audio host is Core Audio, the only option
My playback device is a Behringer UMC 404HD, although I have unplugged everything and just use built in audio but still nothing.
My sample rate is 44.1 throughout audacity, logic and Audio/Midi setup
It’s a while ago now and I can’t be sure as there would have been a gap in time but I think it might have been after I was changing settings to do some streaming on Twitch with voice over zoom. I have checked every setting I can find and everything else works fine. Logic Pro is still working perfectly and I’ve use Zoom and Teams extensively for meetings all with no audio problems.
I’ve also searched this forum but no luck. Anyone have any suggestions?
I suspect the problem is due to one or more of the “virtual audio devices” that you have installed.
I’ve noticed that in recent versions of Audacity (since “PortAudio” was last updated), that if a virtual audio device creates an error in PortAudio, it locks out all audio devices. (PortAudio is the software that Audacity uses to connect to the sound system).
Your system appears to have 6 virtual audio devices installed
It could be any of those causing the problem, but if asked to guess, I’d go for “Apowersoft Audio Device” (simply because we recently had a report that confirmed that a similar problem was caused by that software).
If you want to try running with my guess, uninstall Apowersoft completely, then reboot the computer. Check that Apowersoft has gone. Check that Apowersoft does not appear in “Sounds and MIDI”. Then try using Audacity.
If that doesn’t fix it, or you want to do this the “proper” way, uninstall all of the virtual devices, check that Audacity works, then install the virtual devices back one at a time, checking after each that they have not broken Audacity.
Of the 6! Soundflower I had used before upgrading to Big Sur for recording internal audio so that is now gone. Blackhole is what I replaced it with and I loaded that way after this problem occurred so I am assuming that is ok. EPOC is gone, Screen recording is an aggregate device so should be ok. Zoom is Zoom and then we get to Apowersoft. A quick Google will tell you that it is very difficult to get rid of but I have followed all the instructions I can find and deleted all evidence of it across all libraries. It looks to have gone from the Audio Midi setup and yet I still have the problem. I am away for most of the next days so if I don’t post for a while, I will be back on Friday.

I’ve never seen a real hardware device show up as both a Recording device and Playback device as one device. Usually real hardware shows up like “Built in” device, with separate entries for recording and playback:
If you shut down your computer, disconnect the UMC 404HD, then reboot the computer, can you get Audacity working properly with the Built-in sound card?
I have unplugged everything, just power left in and no change. Still won’t play or record!
File attached. There could still be a rogue from from Apowersoft, but I can’t find it. Or maybe a setting deep in MacOS or Logic Pro? deviceinfo.txt (802 Bytes)
Audacity loads fine, when I hit record I get error code 9997 as per the attached image. I can load a but when I hit play I ger Error opening sound device, again I have attached an image.
I’m primarily a Linux user, so it doesn’t mean much to me either, but perhaps it’s worth trying with everything set to 48000 (instead of 44100) to see if that makes any difference.
I’ve looked everywhere but I can’t see anything set at 48000. Not understanding that file doesn’t help but I have checked every sound option in every program or interface I can find but no luck.
