Mute or Stop Other Audio While Alarm rings

Hello,

I have an alarm application where an alarm rings at the required time. The alarm sound is an embedded wave file in the ressource file and I play the sound using the PlaySound api call.

I would like to give the user the option of muting other sounds that are currently playing on his machine for the duration of the alarm. If this is not possible using the PlaySound api then I would like to give the user the option of stopping or pausing all other sounds and then ring the alarm.

Does anybody have any ideas?

Does anybody know if this is this possible?
