Some Windows users prefer installing vendor or third‑party ASIO drivers (or ASIO4ALL) for lower latency in DAWs.
Always download from the official Fosi Audio website or their support page:
⚠️ Avoid third-party “driver updater” sites — they often bundle malware or outdated files.
Cause: Windows changed the default audio device to a different output (e.g., HDMI or Realtek).
Fix: Right-click the speaker icon → Open Sound settings → Output → Select Fosi Audio Device. Also, check that sample rates match between Windows and the Fosi Control Panel.
