Ubuntu 14.04 and Skype 4.2 installed. I've set up AppArmor using the Skype AppArmor profile from this wiki. When I use AppArmor with Skype, it has no audio. Is anyone using AppArmor successfully with the latest Skype? How can I make this work?

The profile below is what I now use successfully. I commented out a few permissions that I think Skype shouldn't have. If you have problems with this profile, then try removing all hashes (#) after line 15, and reload the profile with apparmor_parser -r /etc/apparmor.d/usr.bin.skype.

I'm curious, what exact steps did you follow to enable this profile? –  Seth Jun 23 '14 at 20:12
@Seth I put the info in the file /etc/apparmor.d/usr.bin.skype and cat /etc/apparmor.d/usr.bin.skype | apparmor_parser -a (and -r to reload) –  Sepero Jun 23 '14 at 20:16
And this is Skype 4.2 not 4.3? And you get audio when disable the AA profile? –  Seth Jun 23 '14 at 20:18
@Seth Yes and yes. It is skype:i386 (version 4.2) from the canonical partner repository. –  Sepero Jun 23 '14 at 20:19
@Sepero, thank you for a working AppArmor profile for Skype 4.3 –  utapyngo Aug 25 '14 at 15:17

You will have to manually review and debug they Apparmor Profile you copied from Arch. My guess is that you can review and make a few (minor) changes.

If you can not do this, then I suggest you put the profile into complain mode and run aa-logprof

sudo aa-complain /etc/apparmor.d/usr.bin.skype

Open and use Skype. Close Skype.

Then run aa-logprof

sudo aa-logprof

Review and accept the changes.

I suggest you review the final profile ;)

Then re-enable the profile

sudo aa-enforce /etc/apparmor.d/usr.bin.skype

I did like you said, and to really be sure, I enabled almost everything aa-complain requested. It's working now. Hopefully I can figure out exactly why I was having the issue before. :) –  Sepero Jun 24 '14 at 10:09
