Casting audio to DLNA device from the command line

Hello,

I'm attempting to setup my workstation to act as a wakeup clock. So far I've successfully scheduled a task with Task Scheduler which wakes up the system and starts playing music, though it doesn't cast the music.

Now I would like to develop this further by casting music to a DLNA audio renderer (DLNA speakers) upon wake.

In explorer it's possible to select a list of music in a folder and right click on the selection and follow the 'cast to' menu item to cast the music to the speakers, however I'd like to do this from the command line so that I can run the command line script from the tast scheduled in Task Scheduler.

How can this be done? Is it possible??
