When this guide applies

Exact FiiO K17. Original K17 previously worked and entered smart idle after playback stopped. It remains powered. The connection is digital/BT/network, not analog Line IN where smart idle is not supported.

Connection scope: USB audio · Optical digital audio · Bluetooth · Wi-Fi / Ethernet network audio. Symptom: Power-on or automatic standby isn’t working.

This is a documented check, not a diagnosis of your equipment. The model name does not confirm the selected input, mode, software or connected partner.

If your exact model or a required setting is unknown, use the “I don’t know” branch below. Do not apply a similarly named model’s instructions.
