Can't stop music on Alexa that I started music on

[u/wdpaynter]

I have been having a strange issue where I can;t stop the music I start on the same device I spoke to/started the music on. But if i speak to an echo device outside of that group, it stops the music. I use (2) Alexas in every room. (1) I speak to and (1) is connected to an amp/speakers via 3.5mm to play music. I have them setup in the same group/room and have settings set to play music only from the one that is connected to amp. I have had this setup for several years, but only have this issue in one room. The particular room has (1) Echo dot and (1) Echo Input (connected to amp). I have deleted and recreated the group. I have reset the echo devices, but nothing works

Any suggestions are welcome

That setup with the Input always gets weird, had one go rogue on me a few months back and the only thing that fixed it was swapping which device was the default speaker in the group
