Hello,

Just thought I'd mention that I've gotten that exact same Error -9996 or sometimes -9997, stating Invalid Device, when I've tried to use Audacity to record some audio. And I got this error AFTER Windows did an update! At this point Audacity (v. 2.3) doesn't see an ASIO driver, and it doesn't work with MME or WASAPI either (get the same error)... although it will playback fine, just won't record!

This is happening on two separate computers... one a laptop and another a desktop... that were working fine beforehand. They use different audio interfaces. Other programs seem to still work fine, although I can't test BIAB on the laptop. I even tried to use Waveasaur instead of Audacity, and it does the same thing.

The point of my butting in here was to mention that this error only showed up (for me anyway) after Windows updated. I've checked all the device settings, and record and playback settings in Windows and Audacity, per the instructions on Google for this error. They're all fine.

One last point is that a third computer, running Win7, is still recording to Audacity without any errors.

Not sure what MicroSoft did, but it sure seems as if some audio programs don't like it.

Again, just mentioning this in case you've gotten a Win 10 update recently.

Hope that this may help in your troubleshooting. Maybe?
