You can start audio at a certain offset with the offsetInMilliseconds key, but I'd like to end it at a certain offset as well. Is there any way to do that?
Based on your description, do you mean:
1. Ask Alexa to play a music station and then set a timer to stop playing after 15 minutes
2. Ask Alexa to play a list of songs and play 1 minute for each song?
Could you clarify a little bit on what you really want? Thanks.
