FiiO K17: select K17 as the enumerated computer media output
FiiO K17 — select K17 as the enumerated computer media output. Use the stated exact hardware and connection scope.
Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Exact FiiO K17. Original K17 is powered, front headphones/PO and USB mode are already selected, and the computer lists K17. Driver prerequisites are satisfied. Computer media is silent because another output may be selected.
Connection scope: USB audio. Symptom: There is no playback sound.
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.
Checks and possible outcomes
Start at scope. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
scope
Confirm the model and connection
Original K17 is powered, front headphones/PO and USB mode are already selected, and the computer lists K17. Driver prerequisites are satisfied. Computer media is silent because another output may be selected.
Look for: Confirm this exact setup and observation before continuing.
- If Yes, I confirm → Inspect source routing
- If No / my setup differs → Continue with source and model support
- If I cannot confirm → More information is required

Inspect source routing
With USB already selected and K17 enumerated, inspect the computer system and player output.
Look for: Observe the named indication or available control; stop if absent.

Choose K17
Choose the connected exact K17 output in both system and player; stop if absent rather than installing arbitrary software.
Look for: Observe the named indication or available control; stop if absent.
