Manufacturer-documented Reviewed 2026-11-09 · Revision 1
Follow these checks in Audio Fix →When this guide applies
Exact iFi ZEN DAC 3. ZEN DAC3 is powered and the computer already lists it as a USB output; compatible driver prerequisites are already met. This is source routing, not a dark-power problem.
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.

Select ZEN DAC3
Choose the enumerated ZEN DAC3 output in the system/player rather than computer speakers. If absent, stop for the exact driver/source instructions.
Look for: Observe the named indication or available control; stop if absent.
