Installationstrin:

1. For desktop users, use native USB 2.0 ports. Always prefer rear-panel ports (direct motherboard connection). Avoid front-panel ports as extended cable routing can degrade high-speed signaling.
2. Connect the Gustard device via USB. Power on. If no "New Hardware" prompt appears, try alternate USB ports. Power-cycle the Gustard USB interface.
3. Run `Gustard_UsbAudio_v4.82.0_setup.exe` (or later versions). Click "Yes" in the User Account Control prompt.
4. Follow on-screen instructions (click Next/Install).
5. If a red error appears stating "Setup requires that the device is...", power-cycle the Gustard USB interface and re-seat the USB cable.
6. Click Finish upon successful installation. Select YES for any additional prompts.

Foobar2000 DSD Native Setup

To enable DSD native playback in Foobar2000, follow these steps:

1. Open the folder `foo_dsd_asio`. Run `ASIOProxyInstall-0.7.2.exe`. Click Next/Install to complete the installation.
2. Launch Foobar2000. Click `File` > `Preferences`.
3. In Preferences, go to `Components`. Click `Install...` and select both `foo_input_sacd.fb2k-component` and `foo_dsd_asio.fb2k-component` from the `foo_dsd_asio` folder.
4. Click `Apply`. Confirm the pop-up to restart Foobar2000.
5. After restart, navigate to `File` > `Preferences` again.
6. Expand `Playback` > `Output` > `ASIO`. Double-click `foo_dsd_asio`.
7. In the `foo_dsd_asio v0.7.2` window:
   • ASIO Driver: Select `Gustard USB Audio`.
   • DSD Playback Method: Select `ASIO Native`.
   • Configure other settings as needed (e.g., DSD to DSD Method, PCM to DSD Method, DSD/PCM Transition).
   Click `X` to close.
8. Go to `Tools` > `SACD` > `Output Mode: DSD`. Click `OK` to complete.

Foobar2000 DSD Playback Troubleshooting

1. Why is ASIO missing under Playback > Output in Preferences?

Årsag: ASIO component not installed.

• Drag `foo_input_asio.fb2k-component` from `foobar2000_DSD 0.7.X` folder into the blank area of Foobar2000's Components panel.
• Click `Apply` > Confirm restart prompt.
• ASIO appears after relaunch.

2. Why is SACD missing under Tools?

Årsag: SACD component not installed.

• Drag `foo_input_sacd.fb2k-component` from `foobar2000_DSD 0.7.X` folder into the blank area.
• Click `Apply` > Confirm restart.
• SACD appears after relaunch.

3. Why does DSD playback fail with this error despite correct settings?

Årsag: Version conflict between ASIOProxy and SACD decoder components.

Løsning: Correct version pairing is crucial. Both must be 0.7.X series.

Fælles problem: Older Foobar2000 installations using SACD component v0.6.X with ASIOProxy v0.7.2.

Valgmuligheder:

• Mulighed 1: Update SACD component per Solution 2 above. If components are locked:
  • Reinstall the latest official Foobar2000 release.
• Mulighed 2: Without reinstalling Foobar2000:
  • Install legacy driver `ASIOProxyInstall-0.6.5.exe`.
  • Search online for verified download sources.
