Windows room correction calibration errors. No known cause

[aweir]

I am attempting to perform room correction on my HTPC using a both a UMIK-1 mic and a Yamaha YPAO mic. It fails in every imaginable way possible quite often. Actually, the list or errors possible is absolutely hilarious. Let's list all the errors shall we?

Microphone level too low.
Microphone level too high.
Overload detected.
Background noise level too high.
Unable to get consistent delay measurements.

Sometimes I luck out and it just works, other times no matter what settings I tweak it just will not work. When using the UMIK microphone, the gain is sett all the way up and the level of the A/V receiver is set to almost THX level, I will still get a "microphone level is too low". Then suddenly it will work minutes later.

What I am using is a Windows 10 PC with on-board Realtek ALC1150 soundchip, with default Windows drivers, since the Realtek driver does not allow microphone calibration. Anyway I am one step away from using a tape measure and the manual room correction in my receiver which is a Yamaha HTR 5730. The problem is that the test tones cycles only last a few seconds per speaker which makes it incredibly hard to get a lock on the reading without a continuous tone. But I guess time is money?? ?

This is using some REQ software that is in the basic Windows 10 package? Is it intended for a usb mic like the UMIK-1? These are test tones generated by that software? You will then use your pc, if successful, thru the 6.1 inputs on the avr? Overall, why are you doing this?

It is the room correction software built into Windows. It is nothing special or out-of-the-ordinary.
I will be using the 5.1 multichannel analog inputs on my receiver. Why, because of the "protected audio stream" of of Netflix and because Dolby Digital will not allow audio processing objects (Equalizer APO) to "hijack" the stream in order to equalize it when it is being sent to an external DAC (A receiver with HDMI/optical/digital coax). Therefore the audio stream can only be manipulated when it is decoded on the same device, the internal DAC, which can therefore only be sent to the receiver in multichannel analog.

The Equalizer APO forums explain it a bit better.
But basically I want to be able to equalize the audio stream when watching Netflix/Blu-ray movies AND have room correction if possible. Otherwise I will have to resort to making all room correction manually with an SPL meter.
