Transcoding video loses audio.

I transcoded the video using hevc_nvenc, and when it reached 100%, the video lost its audio.

However, when transcoding the video with libx265, both the audio and video were intact.

I want to use hevc_nvenc because libx265 consumes too many resources. Is there a way to fix this?
