DJAY2 not working properly with IOS 7 and Pioneer controller

Hi! When connecting ERGO-V to iPad 4 through WeCAi I have no sound from headphones, headphones and master volume controls do not apply.
If I restart ERGO I have the sound appears in the right speaker with the terrible distortion, due to incorrect work of volume regulators.

App: djay 2 (2.2.2)
iOS Version: 7.1
Device: iPad 4
Device: DDJ-ERGO-V (Firmware Ver. 9.41)

P.S. Using the firmware 1.40 has given no result
P.S.S. Everything worked perfectly on iOS 7.0.x

Hi Sasha,

What’s your Audio Devices Setup? Please tap the gear icon, go to “Audio Devices Setup” and take a screenshot.

Hi Warren,
Here is a screenshot

I have no Mac. Tried on Virtual DJ Pro 7.4.1 - sound is present. Everything works. It’s not a hardware problem.
Yes, I use the original adapter.

The same with the Music app…

Ipad4 + ergo-v + wecai. It’s still works, verified.

P.S. My past problem, described above, was solved by itself, there was a problem in software, after the update it all worked

My Ipad Air always says, that the ergo can’t be used, because it needs to mich power, though I am using the WeCai-cable. What do I need to do to get it working???

Anyone know if Djay pro or djay 2 for Ipad still working with Pioneer Ergo?
