PACS is used to expose a device’s audio capabilities in Published Audio Capabilities (PAC) records. PACS is used by nearly all roles, where the Unicast Client and Broadcast Assistant will act as PACS clients, and Unicast Server and Broadcast Sink will act as PACS servers. These records contain information about the codec, and which values are supported by each codec.

If the devices does not have PAC, it's a indication that it does not support LE Audio.

Hi Amanda, thanks for your reply. How does "Unable to find sink PAC" let you know the headset doesn't support BLE?

Hi,

I see this error "<err> bt_bap_unicast_client: Unable to find sink PAC" in the log. It seems the Sennheiser HD 350BT headset doesn't support BLE Audio. Please use the headset that supports BLE Audio.

Regards,
Amanda H.
