Follow these checks in Audio Fix →When this guide applies
Exact Focal Bathys. Exact Focal Bathys is charged and attached by its supplied undamaged USB data cable to a positively capable USB-audio host. The headphone switch is positively ON instead of DAC and USB playback is silent. USB enumeration and host output are checked only after choosing DAC.
Connection scope: USB audio. Symptom: There is no playback sound.
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.

User-reported Dumb Question- Focal Bathys — wired PC subdiscussion
User-reported context: within this original Bathys discussion, one participant reports DAC playback working on a laptop but not on their desktop PC. A reply asks whether USB and the DAC switch position were used.
How this informs the checks: Keep USB enumeration, correct host output and confirmed switch-position prerequisites explicit. The actual steps rely only on the official exact manual, with unknown/unsolved exits.
Limits: One unresolved unverified setup; it does not establish the switch was wrong or that this procedure fixes that desktop. The thread also discusses unrelated movement/ANC complaints, which are excluded. It is not evidence for Bathys MG.
