Enables RDP web clients to receive and play PCM audio from remote sessions through the browser's native Web Audio API, supporting various sample rates.

Highlights:

- Web Audio API backend with AudioContext management and sample buffering
- PCM sample rate conversion
- Extension helpers for web client session integration
- Error handling for audio context creation and playback failures
