Music playback is getting stopped and is not resumed when modem is restarted
This is happening on a Lollipop prototype being used by CAF. When the modem is restarted on this device the audio media framework gets hosed and no more audio clips can be played until the phone is restarted. The reason is that in this device the gonk system process attempts to update audio settings. However, we currently only allow the radio and bluetooth processes to update audio settings . This is easily fixed by granting audio settings permission to the system process too (AID_SYSTEM).  https://mxr.mozilla.org/mozilla-central/source/widget/gonk/GonkPermission.cpp#123

Hsin-Yi, are you ok with Diego's suggestion to grant audio settings permission to System?
(In reply to Dylan Oliver [:doliver] from comment #1) > Hsin-Yi, are you ok with Diego's suggestion to grant audio settings > permission to System? It looks fine to me, but Michael seems the right reviewer.
