Public bug reported: it's not yet clear to me what is wrong. I know that if I fail back to the previous kernel 3.19.0-11 everything works just fine.
The output produced by ubuntu-bug is attached. Please let me know if you think of any relevant command that might help to troubleshoot the issue. PLEASE: consider *NOT* using this kernel if there is such bug (regression??), that would affect many and many users. p.s.: I use HDMI audio pass-trough with Kodi, and it works fine with every other kernel that used so far.
