Hi,

I have a DDRC-22D, and the 22D software and Dirac Live 3.05 on my Windows 10 computer. Computer is connected via USB to DDRC-22D.
Music comes from the same PC via optical cable to DDRC-22D, and from there also optical to a T+A DAC 8 DSD (PCM signal only).
I start the Dirac software from within DDRC-22D software, UMIK-1 is recognized, calibration file loaded. DAC locks automatically to 96 kHz.
But then: whatever I try, in Volume Calibration there is no sound from my speakers. Playing with master volume in either DDRC-22D software, the manual knob on the device or through the master slider does not work. The mike works when I talk in it.
I tried calibrating from another PC (laptop), same issue.
The funny thing is that I can play music through the DDRC-22D. But as I said: no sound in Volume Calibration. When I skip the calibration and try Measurements, still no sound.
Also checked all the microphone and sound settings in Windows 10 on both PC's.
Tried Dirac 3.00, 3.05 and 3.08. Same issue.

What am I doing wrong?

Have you selected the correct input source on the ddrc22?

Yes, the optical led is on, and I can play music through the 22D via the optical cables.

How does the Dirac software send calibration signals to the 22D? It seems that those signals do not reach, or do not go through the optical cable. Everything seems ok in Windows.

Don't have a 22.
Calibration signals are sent via USB to the miniDSP unit.

Sorry to be stating the obvious but on the ddrc22 input have you selected USB?

Thank you, good question. I asked myself the same this afternoon. On the 22D you can not select USB as an input. It's Optical, AES-EBU or SPDIF/Coax. The USB port on the back is for PC control, and can not be selected. So I still wonder where the calibration sounds should come from.

Got it working! By playing music on a low level, and then starting Dirac, the pink noise and the test tones work. Strange, and I informed the support team.
