// The audio-record interface is the companion interface to the audio-playback
// interface and is not meant to be used without it. The design of this
// interface is based on the idea that the slot implementation (eg pulseaudio)
// is expected to query snapd on if the audio-record slot is connected or not
// and the audio service will mediate recording (ie, the rules below allow
// connecting to the audio service, but do not implement enforcement rules; it
// is up to the audio service to provide enforcement). If other audio recording
// servers require different security policy for record (eg, a different socket
// path), then those accesses will be added to this interface.
