Feb 1, 2025February 2025 highlights for xbmc/xbmc: A focused optimization in the audio subsystem delivered via Audio Sink Initialization Simplification. Removed the format verification logic in AESinkAUDIOTRACK to avoid creating and configuring an audio track solely to check compatibility, significantly reducing startup overhead and streamlining sink configuration. This change improves startup time and reduces edge-case failures during initialization. Commit a437ecea3dffbb16ba669bc5318a2f8b8c67c314.
