So you want to be able to resume casting after sending a TTS or sound file?
This was literally proposed 4 hours earlier, and was rejected because it is a repeat request…
Post about trying to fix this:
Text-to-Speech (TTS) stops current media playing without resuming it.
Long standing [FR] for this. Please vote there and add your idea of using broadcast to do it if you like…
WTH is there no option to resume media after a TTS announcement.
