The Five Layers Explained¶
┌────────────────────────────────────────────────────────────────┐
│ LAYER 1: IDENTIFY - Symptom Recognition │
├────────────────────────────────────────────────────────────────┤
│ Objective: Precisely describe what's wrong │
│ │
│ Questions: │
│ • What symptom are you experiencing? │
│ • When did it start? │
│ • Is it consistent or intermittent? │
│ • What changed recently? │
│ │
│ Output: Symptom category (clicks, distortion, crashes, etc.) │
│ │
│ Tools: │
│ → symptom_identification_card.md (quick reference) │
│ → Symptom taxonomy (visual guide) │
└────────────────────────────────────────────────────────────────┘
┌────────────────────────────────────────────────────────────────┐
│ LAYER 2: ISOLATE - Component Localization │
├────────────────────────────────────────────────────────────────┤
│ Objective: Narrow down which component is failing │
│ │
│ Questions: │
│ • Is it hardware, driver, plugin code, or DAW? │
│ • Does it happen with other plugins? │
│ • Does it happen with other DAWs? │
│ • Can you reproduce in minimal test case? │
│ │
│ Output: Fault domain (e.g., "Buffer underrun in ASIO thread") │
│ │
│ Tools: │
│ → Decision trees (diagrams/) │
│ → Isolation test procedures (protocols/) │
└────────────────────────────────────────────────────────────────┘
┌────────────────────────────────────────────────────────────────┐
│ LAYER 3: ANALYZE - Root Cause Investigation │
├────────────────────────────────────────────────────────────────┤
│ Objective: Understand WHY the failure occurs │
│ │
│ Questions: │
│ • What is the underlying mechanism? │
│ • What conditions trigger the failure? │
│ • Are there contributing factors? │
│ • What does the data show? │
│ │
│ Output: Root cause statement (e.g., "Race condition in...") │
│ │
│ Tools: │
│ → Cause-effect diagrams (fishbone) │
│ → Profilers, debuggers, analyzers │
│ → Educational fundamentals (educational/) │
└────────────────────────────────────────────────────────────────┘
┌────────────────────────────────────────────────────────────────┐
│ LAYER 4: SOLVE - Solution Implementation │
├────────────────────────────────────────────────────────────────┤
│ Objective: Apply fix and validate │
│ │
│ Questions: │
│ • What's the appropriate fix? │
│ • Are there side effects? │
│ • Does fix address root cause? │
│ • Is fix properly tested? │
│ │
│ Output: Working solution (code change, config, workaround) │
│ │
│ Tools: │
│ → Protocol-specific solutions (protocols/) │
│ → Testing procedures (tools/) │
│ → Validation checklists │
└────────────────────────────────────────────────────────────────┘
┌────────────────────────────────────────────────────────────────┐
│ LAYER 5: VERIFY - Solution Validation │
├────────────────────────────────────────────────────────────────┤
│ Objective: Confirm problem is truly solved │
│ │
│ Questions: │
│ • Does symptom no longer occur? │
│ • Does solution work across configurations? │
│ • Are there regression issues? │
│ • Is solution documented? │
│ │
│ Output: Verified fix + documentation │
│ │
│ Tools: │
│ → Regression test suites │
│ → Cross-platform validation │
│ → Documentation templates │

🎯 CORE PRINCIPLES¶
The AudioLab Troubleshooting Philosophy¶
╔══════════════════════════════════════════════════════════╗
║ PRINCIPLE 1: VISUAL THINKING ║
╚══════════════════════════════════════════════════════════╝
Every problem has a visual representation.
If you can't draw it, you don't understand it.
Example:
┌────────────────────────────────────────────────────────┐
│ Problem: "Clicks and pops at 128-sample buffer" │
│ │
│ Verbal explanation: "Buffer underruns occur when..." │
│ ❌ Hard to internalize │
│ │
│ Visual representation: │
│ │
│ Timeline: │
│ ┌────┬────┬────┬────┬────┬────┬────┐ │
│ │Buf │Buf │Buf │ ! │Buf │Buf │Buf │ │
│ │ OK │ OK │ OK │MISS│ OK │ OK │ OK │ │
│ └────┴────┴────┴────┴────┴────┴────┘ │
│ ▲ │
│ │ │
│ CPU spike here │
│ (Browser tab opened) │
│ │
│ ✅ Instantly clear what happened │
└────────────────────────────────────────────────────────┘
ACTION: Always create diagrams when explaining issues
╔══════════════════════════════════════════════════════════╗
║ PRINCIPLE 2: SYSTEMATIC APPROACH ║
╚══════════════════════════════════════════════════════════╝
No random "trial and error" troubleshooting.
Follow methodology step-by-step.
WRONG WAY:
┌────────────────────────────────────────────────────────┐
│ "Let me just try changing buffer size... no? │
│ OK, maybe sample rate... no? │
│ Hmm, reinstall drivers? Still no? │
│ Try different USB port? Reboot? Sacrifice chicken?" │
│ │
│ Result: Wasted hours, no learning │
└────────────────────────────────────────────────────────┘
RIGHT WAY:
┌────────────────────────────────────────────────────────┐
│ 1. IDENTIFY symptom precisely (using taxonomy) │
│ 2. ISOLATE component (decision tree) │
│ 3. ANALYZE root cause (fishbone diagram) │
│ 4. SOLVE with targeted fix (protocol) │
│ 5. VERIFY solution (testing procedure) │
│ │
│ Result: Efficient, reproducible, educational │
└────────────────────────────────────────────────────────┘
ACTION: Always follow 5-layer model, document steps
╔══════════════════════════════════════════════════════════╗
║ PRINCIPLE 3: DOCUMENTATION ║
╚══════════════════════════════════════════════════════════╝
Every problem solved = Knowledge captured.
Feed the system for future cases.
WHY DOCUMENT?
┌────────────────────────────────────────────────────────┐
│ ✅ You will forget (human memory is fallible) │
│ ✅ Others encounter same issue (shared knowledge) │
│ ✅ Patterns emerge (recurring problems → systemic fix)│
│ ✅ Onboarding faster (new devs learn from history) │
│ ✅ Prevents regressions (documented fixes stay fixed) │
└────────────────────────────────────────────────────────┘
WHAT TO DOCUMENT:
┌────────────────────────────────────────────────────────┐
│ 📝 Symptom (exact description, when/how it occurs) │
│ 🔍 Diagnostic process (steps taken, tools used) │
│ 💡 Root cause (why it happened) │
│ ⚡ Solution (what fixed it) │
│ ✅ Validation (how you confirmed it's solved) │
│ 📚 Prevention (how to avoid in future) │
└────────────────────────────────────────────────────────┘
ACTION: Use contribution template for every solved issue
╔══════════════════════════════════════════════════════════╗
║ PRINCIPLE 4: CONTINUOUS LEARNING ║
╚══════════════════════════════════════════════════════════╝
Troubleshooting teaches you how the system REALLY works.
Each bug is a lesson in disguise.
LEARNING OPPORTUNITIES:
┌────────────────────────────────────────────────────────┐
│ 🐛 Bug reveals: │
│ • How components interact │
│ • Edge cases you didn't consider │
│ • Performance bottlenecks │
│ • API misunderstandings │
│ • Incorrect assumptions │
│ │
│ → After every bug fix, ask: │
│ "What did this teach me about the system?" │
│ "How can I prevent similar issues?" │
│ "What didn't I understand before?" │
└────────────────────────────────────────────────────────┘
GROWTH MINDSET:
┌────────────────────────────────────────────────────────┐
│ ❌ "Ugh, another stupid bug" │
│ ✅ "Interesting! This reveals how X works" │
│ │
│ ❌ "This is taking too long" │
│ ✅ "I'm learning the system deeply" │
│ │
│ ❌ "I'll just Google the fix" │
│ ✅ "I'll understand WHY this fix works" │
└────────────────────────────────────────────────────────┘
ACTION: After each issue, update educational/ with learnings
╔══════════════════════════════════════════════════════════╗
║ PRINCIPLE 5: COLLABORATIVE KNOWLEDGE ║
╚══════════════════════════════════════════════════════════╝
The system grows stronger with collective contributions.
Your solved problem helps the entire team.
KNOWLEDGE SHARING:
┌────────────────────────────────────────────────────────┐
│ 💬 Weekly troubleshooting review meeting │
│ • Each dev shares one solved issue │
│ • Discuss interesting cases │
│ • Update documentation together │
│ │
│ 📢 Slack channel: #audiolab-troubleshooting │
│ • Post problems in real-time │
│ • Crowd-source solutions │
│ • Archive threads → knowledge base │
│ │
│ 👥 Pair troubleshooting sessions │
│ • Two brains > one brain │
│ • Learn each other's techniques │
│ • Mentor junior developers │
└────────────────────────────────────────────────────────┘
