RME ADI-2 DAC FS: select the intended source explicitly instead of Auto

scope

Confirm the model and connection

The current source actively works, another intended USB/optical source is already connected, and Auto is choosing a different detected input. Front headphones only.

Look for: Confirm this exact setup and observation before continuing.

• If Yes, I confirm → Accept source and clock interruption?
• If No / my setup differs → Continue with source and model support
• If I cannot confirm → More information is required

Accept source and clock interruption?

Changing Source interrupts media and may change digital clocking. Continue only outside calls/recordings with agreement to pause both sources and lower headphone level.

Look for: Explicit informed acceptance is required before the next action.

• If I accept these effects → Pause both sources
• If No / leave this unchanged → Continue with source and model support
• If I cannot confirm → More information is required

Pause both sources

Pause the actively connected current source and intended destination media.

Look for: Observe the named indication or available control; stop if absent.

• If I completed this check → Lower headphone volume
• If I cannot complete this → Continue with source and model support
• If I cannot determine this → More information is required

Lower headphone volume

Reduce the listening level; keep rear line outputs unused.

Look for: Observe the named indication or available control; stop if absent.

• If I completed this check → Choose the actual Source
• If I cannot complete this → Continue with source and model support
• If I cannot determine this → More information is required

Choose the actual Source

In I/O→Settings→Source select USB or Optical matching the already-connected destination instead of Auto. Do not select a USB Rec mode or change Ref Level.

Look for: Observe the named indication or available control; stop if absent.

• If I completed this check → Compare quietly
• If I cannot complete this → Continue with source and model support
• If I cannot determine this → More information is required

Compare quietly

Check the intended source indication and play familiar supported destination media quietly.

Look for: Observe the named indication or available control; stop if absent.

• If I completed this check → Check the result
• If I cannot complete this → Continue with source and model support
• If I cannot determine this → More information is required

Check the result

Does explicit Source selection keep the intended source active and audible quietly?

Look for: Confirm this exact setup and observation before continuing.

• If Yes, I confirm → Checks completed
• If No / my setup differs → Continue with source and model support

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

Checks completed

The requested observation was confirmed in this setup. It does not establish a hardware repair or guarantee another source behaves the same.
