Hi @Fishon401
Welcome to the Sonos Community!
As @AjTrek1 is usually so clued-up on these types of question, I presume they misunderstood your question a little bit.
When sending a Bluetooth feed to an Era 100 stereo pair with a Sub/Sub Mini bonded, the Sub/Sub Mini should be playing along too. The speakers have no real way of knowing/caring that the Bluetooth source is a TV rather than, for example, a phone. That the Sub Mini doesn’t play, when it does with normal music playback, suggests that something is not quite right - it sounds like a software issue, but let’s try some things first.
First, please unplug all three speakers from power for a moment, then plug them all back in.
If that did not fix the issue, please remove the Sub Mini from the room, then add it back on again:
- Settings icon » [relevant room] » Remove Sub » Remove Sub.
- Settings icon » [relevant room] » Connect Sub.
Please let me know how you get on. Thanks.
I hope this helps.
