    Description

      When developed with Qt6.9.0, there is no sound when playing audio files. After testing, I found that this does not exist in older versions (e.g. 5.15.2, 6.5.3). In the cmd debug window, there is an error saying "[SWR@000001D15D8990C0] Context has not been initialized". In my opinion, most likely it is the underlying ffmpeg library calling incompatibility, but there is no better solution yet.
