Hello,
Thank you for reporting the issue where videos converted with Video Converter have no audio after the update.
To help us reproduce and investigate the problem, please provide the full version number of UniFab you are currently using, screenshots of the output settings used when the issue occurred, and the relevant task log files. If possible, please also let us know the audio format of the source file and confirm whether the source video plays with sound normally.
In addition, please tell us whether this issue occurs with all videos or only with specific files. Once we receive this information, we will further investigate the possible audio output issue introduced after the update.
Thank you for your cooperation.
