Behringer X32 Rack (no audio signal coming back from X32 Rack to MacBook while "Calibrating Soundcard")

[buenputter]

Dear REW-users,

I have difficulties in setting up my equipment for measuring my room.

The forum-search for "Behringer X32" or "X32" unfortunately did not help me in resolving this problem.

I installed REW V5.20 and connected my Behringer X32-Rack as audio-interface to my MacBook Pro and applied in
REW > Preferences > Soundcard
the "X-USB" as Output Device and Input Device, but cannot select it below as Output or Input where I just have the option to Select "Default Output" resp. "SPEAKER" and "Default Input" resp. "MICROPHONE". (I guess that this could be the culprit as two buddies using other interfaces CAN select their exact audio-interface here and not just "Default Output" / "Default Input".)


The 1 KHz test-tone from REW reaches my Behringer X32-Rack and I do receive a quite loud signal on the Master Output R, which is looped to Input 2, also receiving a quite loud signal, but no signal is coming back to REW (neither "In", nor "Ref In" => please cf. attached screenshot).

Could you please answer my question or point me to a thread / piece of information dealing with this problem?

Or maybe:
Has this issue been resolved in the latest beta-versions? (I found by search-function beta-versions dated more recently than April 2020, but could not find a download-location.)

Best,
Buenputter

REW works best with very basic sound cards, as described here. If it won’t work with an 8-channel MOTU, your chances are probably less than zero that it will work with a digital mixing console.

If your measurement mic is the USB variety, you can send the Macbook’s audio output to the X32. If that doesn’t work for some reason – the REW Help Files indicate what equipment and connection schemes work with the program. If you want to blaze new ground with something novel, you become the lab rat.

Regards,
Wayne

That is a pity - thank you very much for your prompt answer! :-)

In the Preferences window, under Output and Input, if you click on the the Down Arrow next to Default Output and Default Input; are there any other devices or channels listed there?

Speaker and Microphone are the correct output and input to select, they are just generic names the Java driver uses to describe outputs and inputs. If you select them you should find they offer as many channels as your interface supports.

Hi sam_adams,

thank you for your reply! Apart from "Default Output" and "Default Input" I could also choose "SPEAKER" and "MICROPHONE".

Hi John Mulcahy,

I do find as many channels as my interface supports as well while choosing "Default Output" and "Default Input" as while choosing "SPEAKER" and "MICROPHONE". My interface receives the output from REW and the loop-back-channel does receive the 1kHz-signal, too. Unfortunately, the signal is not coming back to REW. :-(
I can adjust the signals within my interface that they are that hot, that they are clipping, but there is still no signal coming back to REW (-484.7 dB).

Make sure that REW is allowed to access the microphone in the Privacy settings ("microphone" means any audio data input). Normally you will be prompted to allow access when REW first asks for input data, but if you have previously not allowed it you may not be prompted again. When access is not allowed the OS just sends zeroes, which gives the -484.7 dB level readings.
