AudioHibernateFix

A lightweight diagnostic tool that checks and resolves Windows audio issues that may occur after waking from hibernate or sleep.
Designed for simplicity, clarity, and readability.

Overview

Some Windows builds historically exposed a fast‑resume initialization policy that could cause the audio subsystem to fail after waking from hibernate.
Symptoms included:

• No sound output despite devices appearing present
• Audio services running but not properly bound
• Audio endpoint failing to re‑initialize

AudioHibernateFix performs two checks:

1. Audio Service Health Check
   Ensures Audiosrv and AudioEndpointBuilder are running.
   If either service is unhealthy, the tool safely restarts the audio stack.

2. Power Initialization Policy Check
   Detects whether the legacy SUB_DEVICE POWERLEVEL policy exists.

   • If present → the tool corrects it
   • If not present → the tool reports that your Windows build uses the modern full‑device reinitialization model

Features

• Polished menu interface with color‑coded output
• Two diagnostic modes:
  • Simple Check — concise health check
  • Detailed Check — definitions, raw states, and verbose diagnostics
• Safe, non‑destructive fixes
• Clean exit behavior
• GUI‑ready structure for future versions

Usage
