Does it use the alarms's volume level for playing the podcast or does it use the media volume level? Strangely it does not seem to support playing media/playlist/radio from google music as alarm. Even more strangely it all requires to be set up using Google Assistant, I mean is there someway to configure it without using voice commands to the Google Assistant, which is a tedious and cumbersome interface for such a complex functionality.
