FiiO K13 R2R: select the enumerated K13 R2R in computer media output
FiiO K13 R2R — select the enumerated K13 R2R in 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 K13 R2R. The exact K13 R2R is powered and enumerated by the computer; compatible OS/driver prerequisites are already met. USB IN and PO are already selected but computer media is routed elsewhere.
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
The exact K13 R2R is powered and enumerated by the computer; compatible OS/driver prerequisites are already met. USB IN and PO are already selected but computer media is routed elsewhere.
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 IN and PO already selected, inspect the computer system and player output.
Look for: Observe the named indication or available control; stop if absent.

Choose the exact K13 R2R
Choose the enumerated K13 R2R in system/player routing; stop if absent rather than installing arbitrary drivers.
Look for: Observe the named indication or available control; stop if absent.
- If I completed this check → Compare quietly

Compare quietly
Play familiar PCM media with front headphone volume low and rear line outputs unused.
Look for: Observe the named indication or available control; stop if absent.

Possible result
More information is required
An unknown state is not a diagnosis. Record the last visible indication and consult the exact model instructions.
insufficient data
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
Possible result
Continue with source and model support
Keep the source, connection and last observation. Do not reset, open equipment or change full-scale output to compensate for an unconfirmed result.
next support
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
Possible result
