Description Luigi Baldoni 2016-10-26 09:23:07 UTC

And by stopped working I mean kmix showing the dummy output but no apparent error when loading the module.

The card in question is:

Audio device [0403]: Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller [8086:1e20] (rev 04)

as shown by lspci.

No problem whatsoever with kernel-desktop-3.16.7-42 or (to my memory) any of the previous ones.

Comment 1 Takashi Iwai 2016-10-26 13:31:51 UTC

So, when you boot the old kernel with the updated system, it starts working again?

If so, run alsa-info.sh with --no-upload option on both good and bad kernels, and attach the outputs to Bugzilla (don't paste).

Comment 2 Stefan Backens 2016-10-26 13:45:47 UTC

It seems that kernel-desktop-3.16.7-45 breaks POSIC ACL support: Logind cannot set access rights to the relevant device files and writes the error message "Invalid argument" to the log. (setfacl gives me the same error message when I try to set ACLs for a regular file.)
Video playback fails with an "Access denied" error, too.

Booting with the previous kernel-desktop-3.16.7-42 makes these problems disappear.

Stefan Backens, can you open a seperate bug please

Correct.

See attached log.

Comment 6 Takashi Iwai 2016-10-26 14:25:26 UTC

Thanks.  So this is a generic breakage, not specific to the audio.  The alsa-info output shows that the values could be read by root.

As Marcus suggested, could you open another bug report?  It will clarify the issue more without garbage information.  Eventually we'll close this as the dup of that bug.

Feel free to put me to Cc when you open another bug.  Thanks.

See bug 1007035

Comment 8 Takashi Iwai 2016-10-26 14:33:07 UTC

OK, let's close this and track there.
