I'm a bit late to this thread but I only just found a solution to a very similar problem - the machine in question is actually running 1803 Build 17134.167.
It has a Realtek High Definition on-board "sound card" and I found that when I tried to use my VERY old but likeable Wave Repair software, whereas before the update to 1803 everything worked, after the update I got error messages when I tried to record. I played around with all sorts of drivers and configurations for many hours, but finally found the issue, which makes no sense to me but is a repeatable fix.
Note that I hadn't had occasion to use Wave Repair for quite a while, so I'm not exactly sure whether it was the update to 1803, or another subsequent CU that caused the problem. I know it was all working in 1709 (OS Build 16299.431) and the next time I tried it was, as I said, in 1803 (OS Build 17134.167)
Anyway, at some time after the update to 1803, if I tried to record from the audio stream playing on the PC (NOT a microphone) I got this:
Now, habitually, I set all my Privacy options in Windows locked down as securely as I can which means OFF in most cases!
I tried another (free) sound mixer program and got similar error messages. Note that all the while I could listen to the sounds, just couldn't record them!
SOLUTION
In Windows 10 1803 (OS Build 17134.167) and possibly before, the sound card is not accessible for recording UNLESS
Settings > Privacy > Microphone is set as follows:
How to Allow or Deny OS and Apps Access to Microphone in Windows 10
Microphone access for this device is ON - originally I had it switched OFF
Allow apps to access your microphone is ON originally I had it switched OFF
All the "apps which can access your microphone" may be turned OFF unless you know you use them.
Now looks like this:
This allowed Wave Repair to work correctly exactly as it had before the update to 1803.
@Bree, @Brink If I've posted this "happy helpful tip" in the wrong thread, please do move it!
