When this guide applies

Exact Scarlett 2i2 4th Gen or Scarlett Solo 4th Gen, not earlier generations. For Solo, Air applies only to the microphone input. Exact Focusrite Scarlett 2i2 4th Gen. Installed Control 2 already recognises the exact interface; valid supported input already selected (Solo microphone only). No sample-rate change or recording interruption. Only normal external user controls; no reset, firmware installation, internal repair, mains alteration or earth lifting.

Connection scope: USB audio. Symptom: An option or codec is missing.

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.
