Arcam AVR11: compare CD Direct only for the beginning of a verified constant-PCM source
Only track beginnings are lost at a fixed-format PCM CD source; CD Direct Off and no mixed/bitstream source.

Follow these checks in Audio Fix →When this guide applies
Only track beginnings are lost at a fixed-format PCM CD source; CD Direct Off and no mixed/bitstream source.
Connection scope: Optical digital audio · Coaxial S/PDIF digital audio. Symptom: Audio keeps cutting out.
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 missing sound specifically the beginning of otherwise continuous tracks from the identified digital CD source?
Ongoing cuts, an unstable link or a streaming service has another path.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Do exact source documents confirm it sends only a consistent PCM format on this optical/coaxial connection?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-1
Do exact source documents confirm it sends only a consistent PCM format on this optical/coaxial connection?
Unknown output, Dolby/DTS bitstreams or a device that can change formats stops here.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Is CD Direct explicitly Off for this named input?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-2
Is CD Direct explicitly Off for this named input?
Do not change an already On or unknown value.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Do you accept bypassing the format-change mute guard only for this permanently fixed-PCM source?
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-3
Do you accept bypassing the format-change mute guard only for this permanently fixed-PCM source?
Unwanted noise can occur if a changing-format source is later used. Keep levels comfortable and retain Off for reversal.
Look for: Confirm the actual prerequisite or observation. Stop safely if unknown.
- If Yes, confirmed → Set only this input Input Config > CD Direct to On
- If No → Stop at the unconfirmed condition
- If I do not know / cannot check → A required fact is unknown

step-4
Set only this input Input Config > CD Direct to On
Do not apply it to another input, change formats, reset settings or raise playback level.
Look for: Perform only the stated operation, then confirm it was possible.
- If I completed this → On an ordinary replay, is the known track beginning now retained?
- 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
On an ordinary replay, is the known track beginning now retained?
Choose Unknown if no later observation is available. This is not a measured gapless-playback claim.
Look for: Confirm the actual prerequisite or observation. Stop safely if 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.
