Hi, 

here’s my Setup:

PA with semiprofessional mixer; Sonos Port as Input for PA; 2 older TVs; Amazon Fire TV Cube (2. gen.); HDMI Splitter for the 2 TVs, Bluetooth Connector 

What i try to reach:

Playing Youtube on the TVs while streaming the sound to the Sonos Port

Problem:

The connection between Amazon Fire TV Cube and Sonos Port is via bluetooth and extremly prone to failure. 

Does anyone have a better idea to solve this?

Thx, Kon.
