maxadamo, thank you for reporting this and helping make Ubuntu better. Could you please test the latest upstream kernel available from the very top line at the top of the page (the release names are irrelevant for testing, and please do not test the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue.
If the test did not allow you to test to the issue (ex. you couldn't boot into the OS) please make a comment in your report about this, and continue to test the next most recent kernel version until you can test to the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags by clicking on the yellow circle with a black pencil icon, next to the word Tags, located at the bottom of the report description: kernel-fixed-upstream kernel-fixed-upstream-3.XY-rcZ Where XY and Z are numbers corresponding to the kernel version. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-3.XY-rcZ Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Tags added: latest-bios-f3 ** Description changed: - it's not yet clear to me what is wrong. But I know that if I fail back - to the previous kernel 3.19.0-11 (or any 3.16 older kernel) 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 I used so far. + With kernel 3.19.0-12 HDMI audio breaks. If I use the previous kernel + 3.19.0-11 (or any 3.16 older kernel) everything works just fine.
