 Phase will show no effects when viewing a single subwoofer. Phase only has an effect when two or more speakers are played together. |
Oh, I didn't know that
I really thought that modifying the sub phase would modify the SPL at my listening position. Isn't the phase used to work against standing wave effects (peaks and valleys)? I do see some differences (<10dB) when going from 0 to 90 or 180.
Could you explain it to me or provide a link to a full explanation?

Your calibration file is not valid when using digital out. The file is used to compensate for the loopback of analog line-out and line-in. I would work on the analog problem and see if you can sort that out. |
I tried to fix my analog problem but it's not easy. The problem is that the jack connector in my PC is a bit loose and the PC itself generates high-frequency noise. It works ok sometimes and badly most of the time, but it's ok for low-frequency measurements. I think that I will have to buy an external soundcard sooner than expected

Either way, I don't see how you're getting an output when your Master volume is at zero (as shown in your pics). |
Well, I don't understand it either but the reality is that the master volume doesn't have any effect on my digital output. Looks like it works like a pre-amp output. I only have to enable the SPDIF output in the
Options->Advanced Controls in the XP Master Volume window.
The master volume has an effect on the analog output of course. And there I get correct measurements and no
loopback problems.

Have you checked the soundcard own application for monitor modes being turned on? |
No, actually. The sound card is a ESS Maestro3i and I can't remember having any specific application for it. But I will double-check it !
