Mute sound in Kindle fire HD

Hi,

Very simple question, but I have had reports that the mute button I added to a game doesnt work on a Kindle fire HD, (seems to work on my mobiles and my desktop) - but I don't have a kindle Fire HD to test with.

The game is finished and has been submitted for QA on FGL, but this has come back, I'm currently doing it using the 'Set silent' from the Audio object.

Should I also be doing it another way?

Thanks,

Alan

Well for now I have just added another action to set the volume so low you cant hear it, but I assume there must be a better way.
