Asus Xonar STX II - No sound on fresh Kodi 14.2 - Ubuntu 14.04 installation

I've installed Kodi (XMBC) mediacenter, by using "Kodibuntu" installation, which is based on Ubuntu 14.04. Onboard sound card worked out of the box. Few days ago I've got new Asus Essence Xonar STX II sound card, I disabled onboard sound, and even though everything looks good (by looking at various alsa commands and /proc/asound/* directory), there is no sound at all, neither to speakers, nor headphone.

What I tried:
- upgrade to Ubuntu 14.04.2 and linux kernel 3.16 (no result)
- install Deadbeef audio player, and set audio output to "Asus STX II (Multichannel) with direct ...." (no result)

Even though i could not find any warning/error, still there is no sound on my speakers/headphones. Yet, sound card is working properly, because when I upgrade to linux kernel 3.17 it worked correctly. However, due to breaking other things, I can't stay at 3.17.

As far as I know, there is no pulseaudio on this installation. I tried to reinstall Kodibuntu numerous times, while testing, also I tried with fresh installation of Ubuntu 14.04, but no success.

Outputs are not muted. I've run alsamixer and check master volume and mute status. And I didn't forget to bring molex (power supply) to the sound card, which is required for internal amplifier.

Output of alsa-info.sh is here:

Output from /proc/asound/card0/pcm0p/sub0 directory, while playing 192 kHz track in Deadbeef with direct output to "hw:0,0".
