media-hub-server will likely fail to play all kinds of files, not just
those in /usr/share/sounds because we have an explicit deny rule that is
overriding our rule to allow mmap of /tmp/orcexec.
** Summary changed:
- Cannot play sound files in /usr/share/sound/** folder due to apparmor
permission issue
+ Cannot play sound files due to apparmor permission issue
** Description changed:
In the clock app we read /usr/share/sounds/ubuntu/ringtones and when
trying to use MediaPlayer{} or Audio{}, it works on the desktop but
fails on the device. Doing a quick grep DEN /var/log/syslog reveals the
following apparmor denials,
Aug 15 11:16:58 ubuntu-phablet kernel: [ 3968.875354] type=1400
audit(1408094218.079:104): apparmor="DENIED" operation="file_mmap"
profile="/usr/bin/media-hub-server" name="/tmp/orcexec.CLp5yf" pid=5825
comm="aqueue:src" requested_mask="m" denied_mask="m" fsuid=32011 ouid=32011

On talking to jdstrand,
2:09 PM <jdstrand> ah
2:10 PM <jdstrand> we have this rule:owner /tmp/orcexec* m,
2:10 PM <jdstrand> but it is overriden by this: audit deny owner /** m,
2:10 PM <jdstrand> nik90: can you file a bug against media-hub?

+ Original summary: in /usr/share/sound/** folder
