Sound export in 44100 Hz instead of 48000 Hz, why? I started to use Blender as a solution for video editing, very powerful and agreeable. Nevertheless, I have a bug that I can't resolve. The sound of my  video is in 48kHz, my users preferences are also in 48kHz, but when I export in H264 the final editing, the sound goes out in 44kHz.

I also exported the sound only in wav, and same issue. Any idea where this issue comes from?
The sound frequency for the project is set here:



change it to 48000 Hz.
