Follow these checks in Audio Fix →When this guide applies
Existing HDMI video works; an intended line-level analogue source already occupies an identified AUDIO 2–4 pair.
Connection scope: Analog line / headphone audio. Symptom: Switching between devices 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.
Checks and possible outcomes
Start at step-0. Follow the link that matches what you actually observe. Alternative branches are not a single sequence of actions.
step-0
Is the intended HDMI picture already working on this identified input?
No HDMI/HDCP/cable capability is created by the audio selector.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Is the wanted line-level source already correctly connected to the identified AUDIO 2, 3 or 4 analogue pair?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-1
Is the wanted line-level source already correctly connected to the identified AUDIO 2, 3 or 4 analogue pair?
Raw PHONO, unknown wiring or a digital connector is outside this analogue route.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → May this selected HDMI input use that separate audio source instead of its present audio?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-2
May this selected HDMI input use that separate audio source instead of its present audio?
Retain the old assignment and keep initial levels low.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Select that already identified HDMI input
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-3
Select that already identified HDMI input
Do not change another source assignment.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → In System > Audio In, choose the verified AUDIO 2, 3 or 4 input carrying that analogue source
- If I could not do this → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-4
In System > Audio In, choose the verified AUDIO 2, 3 or 4 input carrying that analogue source
Leave physical connections and TV Audio Input unchanged.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → Does the intended HDMI picture now accompany the intended analogue programme?
- If I could not do this → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-5
Does the intended HDMI picture now accompany the intended analogue programme?
Selecting a jack does not verify an unknown source output level or repair a cable.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Checks completed — report the actual result
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

Possible result
Checks completed — report the actual result
Completion does not automatically mean the problem is solved. Report what actually happened; no physical test or measured repair is claimed.
steps completed
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
Possible result
Stop at the unconfirmed condition
A required setup or response was not confirmed. Retain the actual observation and consult the exact source/partner manual or official support. Do not escalate to a reset, update installation, internal repair or unsafe wiring change.
next support
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
Possible result
A required fact is unknown
Confirm the actual model, connection, partner capability and state before continuing. Do not guess a menu, interrupt an installation or modify a live source by trial and error.
insufficient data
Reaching this result does not mean the issue is solved. Only your own feedback can report improvement.
