Summary

This PR add speed and pitch playback customition to powerplay. it also improves the audio playback experience in the PowerPlay sample app by resolving buffer size issues and handling hardware limitations during PCM Offload mode. It introduces dynamic UI controls that adapt to the file's sample rate and mode, and adds a polished reset feature with smooth animations.

Changes

C++ Engine (PowerPlayMultiPlayer.cpp)

• Increased Buffer Capacity: Increased the buffer capacity to 8192 frames to support variable playback speeds without triggering ErrorIllegalArgument due to insufficient buffer size.

Jetpack Compose UI (MainActivity.kt)

• Dynamic Control Enablement: Implemented a matrix of rules to enable/disable speed and pitch sliders based on the current performance mode (MMAP vs Classic Offload) and the file's sample rate.
• Informative UI Labels: Added text indicators next to sliders to explain why they are disabled (e.g., "Requires API 37" or "Not supported for 44kHz in MMAP Offload").
• Reset Button: Added a "Reset to Defaults" button that appears only after modifying values and letting go of the slider.
• Smooth Animations: Refined the appearance and disappearance of the Reset button with fade and slide animations for a premium feel.

Offload Limitations Matrix

The following table details the controls enabled in different offload scenarios:

How to Test

1. Open the PowerPlay sample app.
2. Load files with different sample rates (44.1k, 48k, 96k).
3. Switch between different performance modes (Low Latency, Power Saving, PCM Offload) and toggle MMAP.
4. Verify that the sliders are enabled/disabled according to the matrix above.
5. Verify that the Reset button appears smoothly after releasing a slider and works as expected.
