this is frustrating. I will now maybe reinstall 14.04.4 an try again ....
I know usb unit supplier is not supporting linux, but mac is on the list and it worked perfect with 14.04.
thanks for the hints sofar!

Listen to me. Install Ubuntu 14.04.4 64 bit LTS again on your desktop or laptop.
DO NOT upgrade the Linux kernel any higher than 4.2.x AMD64. It is Linux kernel 4.4.0 AMD64 that might be causing this problem with some high end USB 2.0 audio DACs and headphone amplifiers. So, do not download and install the next Ubuntu 14.04.5 64 bit LTS Hardware Enablement Stack right away. This is coming in August 2016.
I am not giving up on Ubuntu 16.04 64 bit LTS. I own a Sager NP8657 [Clevo P650-RE3] gaming laptop with it installed. It works with my Chord Mojo portable DAC and headphone amplifier. So, I might test future patches and updates by plugging in my Oppo Digital HA-1 until this problem is solved. When it is indeed solved in due time, then I will reinstall Ubuntu 16.04.x 64 bit LTS on my mid-2015 Zareason Zeto desktop PC system again.
I will keep people in this thread and over at Ubuntu Forums up to date about my findings.
st1:
now downgraded to 14.04,4 without any updates and usb device audio is visible without any trics. Great !
I just wonder what updates I can take without killing the system again.
Am I safe if I get updates only until August and stop updating before the
14.04.5 64 bit LTS Hardware Enablement Stack, that is coming in August 2016.
or when to stop updating ?
the ubuntu errors fix team should get more pressure that critical usb audio not working
wellywu:
If I were you, do not download and install Ubuntu 14.04.5 64 bit Hardware Enablement Stack in August 2016. Just make sure not to download and install Linux kernel above 4.2.x AMD64. If Ubuntu 14.04.5 64 bit LTS ships with Linux kernel 4.4.x AMD64, then do not download and install it manually. Canonical, Ltd. does not force you to download the LTS Hardware Enablement Stack upgrade; that must be done manually.

Awesome Donkey:
It seems to me the Ubuntu 16.04 LTS release has been plagued with problems. They just recently released a fix via kernel update for a XHCI USB issue (which was fixed in 4.6.2 and above) I've had with Ubuntu and other distros for a year and a half now.
