Audacity 2.3.0 not recording

First, thanks for the great software, I’ve used it loads in the past for games.

Right now though, I am having difficulties getting it to record voice. it gives me the following error:

I went to try it again and it seems that I can record but I have to select either the microphone or the speakers in the pull down box which allows me to EITHER record or have playback.

Does anyone have any ideas what I should do?

Try setting “host” to WDM in the Device Toolbar.

Thanks for the reply.
There is no WDm but there is this:

It gives me an error and the original pull down is blanked now.

Sorry, I meant “set host to MME” (which uses WDM drivers).
If there is no input option with host as MME, then either some other app is hogging the audio device, or there’s a problem with the device drivers.
