Identify which function succeeds
A headset or remote can offer several functions over a Bluetooth connection. The Bluetooth SIG’s AVRCP specification concerns audio/video control and explicitly says it does not itself handle audiovisual streaming. A device responding to a play command is therefore useful evidence about control, rather than proof that sound is travelling through the intended audio profile. Record those outcomes separately when describing a fault.
Distinguish controller and audio roles
AVRCP defines controller/target interactions, while audio distribution belongs to another profile arrangement such as A2DP. A product may implement both, but their coexistence is an implementation requirement rather than something inferred from a generic Bluetooth logo. Check the exact source and accessory documentation for the functions they support. A paired-device name alone cannot settle every codec, control or output capability.
Check output selection as well as pairing
On the actual source device, confirm which audio output is selected using its documented interface. If television speakers continue to play while accessory buttons work, preserve that observation instead of immediately re-pairing every device. Keep microphone or call modes distinct where relevant, because a conversation workflow may use another configuration from ordinary media listening. Avoid applying a computer’s menu path to a television box.
Test a narrow combination
Use a familiar lawful item at a comfortable volume, then compare only the intended output or accessory. Note model names, software and the functions that work. Reconnect through the manufacturer’s supported steps if needed and restore previous settings after an inconclusive test. This reference does not guarantee codec negotiation or remote interoperability between arbitrary Bluetooth products, and it does not verify UK IPTV playback through a specific accessory.
Questions, answered
Do working Bluetooth pause buttons prove the headset is receiving audio?
No. Remote control and audio distribution are distinct functions. Check the selected output and supported profiles for the actual source/accessory pair.
