Bugzilla – Bug 1006983
snd_hda_intel stopped working on kernel-desktop-3.16.7-45
Last modified: 2016-10-26 14:33:07 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.
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).
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
Created attachment 699391 [details] alsa-info.sh for kernel 3.16.7-42 and 3.16.7-45

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
OK, let's close this and track there. *** This bug has been marked as a duplicate of bug 1007035 ***
