Worked on enhancing the Media Framework and Audio Management for the Samsung/TizenRT repository, focusing on runtime stability and improved audio control. Developed a new SoundManager class in C++ to centralize audio management, ensuring consistent volume and focus behavior across the system. Updated the recorded audio path to support a revised recording workflow and refactored the media player in C to handle focus changes more robustly, particularly during paused states. These changes reduced audio glitches during playback and focus transitions, laying the groundwork for future audio features while maintaining stability and avoiding regressions in existing embedded systems functionality.
