Audacity not recognising input 3 or 4

[roadsterUK]

As I have said in answer to so many posts you should run mmsys.cpl and look at the tab which shows recording devices. Any device which is listed as plugged in and enabled should be selectable as an Audacity input device. If this is not so please post a screen snapshot of the sound recording devices window overlaid on the Audacity drop down. For example:-

In this dull example the top three items are just loopback of outputs, line in and stereo mix don't list because they are respectively not plugged in and disabled.

I haven't got any problems there. My UMC404HD is selectable, which has all three mics running through it. In that recording windows tab the third mic is detected (the little green bars rise). However the third mic doesn't work in audacity.

OK I think that narrows it down to an Audacity problem but I would try removing some of the other device and drivers, particularly the Realtek ones which have been shown to cause problems. Also as one error hints at sample rate issues try testing with device and audacity defaults set to a lower sample rate. It would also be useful to know if the problem is still there with ASIO drivers but I realise that you might not be able to compile Audacity with ASIO.

What are the sampling rates, in the "Windows Sound control pane" set at for the
UMC404HD recording device,
UMC404HD recording device,
and
Realtek High Definition playback device?

Sorry for slow response, floods knocked out power. If its not bushfires here its floods.

UMC404HD recording device - 44.1K
UMC404HD playback device - 44.1K (greyed out cannot change)
Realtek High Definition playback device - 44.1K

The realtek playback was 48k - changed to 44.1K - worked for like 1 sec then audacity crashed and same error continues now.

Well that solved one issue, but caused another. Once I installed the ASIO driver the recording and playback options changed. I now have two new recording options for IN 1+2 and another for IN 3+4.

The seem to work perfectly so I can get sound from input three now. The problem is that I can only select 1+2 or 3+4. Not all 4 inputs together.
Under recording channels where I could previously select up to four, now only has mono and stereo.

Have updated audio device info

OK found a work around/solution. Steve it was actually from reading one of your other responses elsewhere so thanks.

I downloaded Voice Meeter - ran IN 1+2 as hardware input 1 then IN 3+4 as hardware input 2 - then in audacity selected Voicemeter as the recording device and all three mics are working now.

cheers.
