With a lack of a wired PA system we are utilizing speakers connected to few Linksys RE6700 devices (that we were already using as WiFi extenders) to make audio play in different areas of a building. We simply use Windows 10 Cast to Device feature in order to do so when we need to.
What we want now is to be able to automate so that we could play a specific MP3 file (say the college anthem) at a specific time of the day. I have not found a way to invoke this command so that I could possibly do the automation using Task Scheduler. I'm open to using a lightweight third-party tool to do this also.
