If your device is not recognized or you need ASIO functionality, follow these steps to ensure a complete installation:
Download: Obtain the driver package from a reputable hardware vendor like Hifime or the official site of your DAC manufacturer (e.g., Nvarcher or DLHiFi).
Run Setup: Extract the .zip file and run Setup.exe (or Setup64.exe for 64-bit systems).
ASIO Control Panel: Once installed, a "BRAVO-HD" or "Savitech" control panel application will typically appear in your system tray. This allows you to adjust Buffer Size to prevent pops or clicks during high-res playback.
Verification: Open Device Manager, expand "Sound, video and game controllers," and ensure the device appears as "SAVITECH Bravo-HD USB Audio" or similar. Troubleshooting Common Issues
Device Not Recognized: Try a different USB port or cable. Ensure the device is selected as the Default Playback Device in Windows Sound Settings. The Savitech SA9123L is a high-performance USB audio
No Sound Output: For modules with physical switches, check the DIP switch settings on the back of the board. These often toggle between Microphone and Line Input or select gain levels.
Distorted Audio: If you experience distortion, increase the buffer size in the ASIO control panel or ensure your software sampling rate matches the hardware (192KHz). Nvarcher SA9123L USB Audio Streaming Controller
