AudioService: fix playback capture permission check
Fix permission checks when registering a dynamic audio policy
of type loopback+render for usage VOICE_COMMUNICATION.
Previous checks were assuming that the policy was created with
allowPrivilegedPlaybackCapture flag which should not be a pre requisit.
The conditions to allow capture of VOICE_COMMUNICATION playback (loopback+render
mode) are:
- Having permission MODIFY_AUDIO_ROUTING (implied by ability to regiter a DAP).
- Having permission CAPTURE_VOICE_COMMUNICATION_OUTPUT.
- The capture format is compatible with capture by system requirements.
- The playback client or app did not opt out from capture by system.
