Play an audio file with a notification

[fromage9747]

It would be great to have the ability to play an audio sound with each notification. Like on an error notification to play an error type sound.

had a thought that this might have been implemented. Is there any way to hook into the notification and play and audio with an extra directive?

At this stage, I would need to go through my app and manually add another method to play and audio file

@flauc Is there any way that I can hook into your service via a custom service/directive to detect when one of the notification methods is being used and then play an audio file?
