Comment 4 for bug 1626611

The explicit /dev/ denial was to fix a noisy denial that was confusing users and so we decided to silence the denial. Due to the way apparmor 'deny' works, you can't undo an explicit deny rule (deny rules are evaluated after allow rules).

There are a few ways forward:
1. fix webbrowser-app's sed to strip out this problematic rule
2. remove the problematic rule from the microphone abstraction. This will cause QAudioRecorder apps to trigger the spurious log entry and reintroduce potential confusion
3. use 'camera' without 'microphone'

Due to the way hybris works, '3' might work, but it wouldn't on non-hybris systems. I suggest doing '1'-- this keeps the changes localized to webbrowser-app's packaging. We've not seen other reports for click apps in several years, so this seems safe.

FYI, on snappy we have taken the stance that we will almost never use explicit denies because of issues like this bug, so this issue should just go away.
