Please Help, -9996

I’m getting this error code, i’ve tried everything. Nothing has worked. I am perfectly able to record Mic Audio, but not loop-back.

OS: Windows 10
Windows WASAPI
Version: Audacity 2.4.2

Please attach your “Audio Device Info” (see: https://manual.audacityteam.org/man/help_menu_diagnostics.html)

I even tried going back a version.

Did that make any difference?
If not, go back to 2.4.2 and we’ll see what we can do.

It didn’t, I went back and got the same error code… This is a real big issue, because i’m doing sound design for a video-game and may be fired if I don’t finish these sounds.

Try unplugging your headset, then launch (or shut down and relaunch) Audacity.
In the Device Toolbar, select “MME” as “host” and “Stereo Mix” as the recording input.

Stereo Mix recorded absolutely no sound, I don’t have speakers on my computer.

You’re using a desktop / tower computer rather than a laptop?

Do you have any conventional (wired, non-USB) headphones that you could plug in?
