/avr:check

Run a pre-flight system check to verify all hardware is connected and working.

Arguments

None.

Workflow

Step 1 — Run check_system

Call the check_system MCP tool. This runs all pre-flight checks in parallel:

• Config: Valid config.yaml present
• miniDSP: USB device connected + minidspd daemon reachable
• Denon AVR: AVR reachable (with auto-discovery if host not configured)
• Signal Path: DSP source/preset matches config (if configured)

Step 2 — Report results

For each check, report:

• Pass/fail status
• Detail (what was found)
• Error message and fix suggestion if failed

Format as a clear checklist.

Step 3 — Troubleshoot failures

If any check failed, provide specific debugging guidance:

• Config: Suggest running /avr:configure to configure.
• miniDSP USB: Check USB cable, try different port, check lsusb output.
• miniDSP daemon: Check if minidspd is running (systemctl status minidspd).
• Denon AVR: Check power, network, try ping. Suggest /avr:configure to configure host.
• Signal Path: Explain the mismatch and what to do about it.

Step 4 — Overall verdict

If all checks pass: "System is ready for calibration." If some fail: "N of M checks failed. Fix the issues above before calibrating."

Important rules

1. Always run check_system first. Don't try to manually check things.
2. Be specific about fixes. Don't just say "check the connection" — say which cable, which port.
3. Suggest /avr:configure if config is missing or incomplete.
