Follow these checks in Audio Fix →When this guide applies
Exact FiiO KA17. KA17 headphones work but remain too quiet in positively L gain. Local menu controls are understood,SPDIF OFF,D.MODE unchanged and no hearing-protection cap is bypassed.
Connection scope: USB audio. Symptom: Playback is too quiet or uneven.
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.

Accept increased headphone gain?
H gain can abruptly increase loudness. Continue only with agreement to pause, reduce the current level first and compare cautiously. Do not enableDesktop mode as part of this comparison.
Look for: Explicit informed acceptance is required before the next action.
- If I accept these effects → Pause source media
- If No / leave this unchanged → Continue with source and model support
- If I cannot confirm → More information is required
