In my personal deck I’ve got several cards that are audio only on the front. I’d like the ability to add an indicator that lets Anki recognise this is a card that I require audio for. If the audio on my PC/phone is off then these cards should automatically be rescheduled.
As a workaround, you can put such cards in a dedicated deck which you won’t review unless you have the sound turned on.
An easy way to do this on the fly is to create a filtered deck with “[sound” in the search
