Blender crashes when trying to export a mixdown from Render -> Render Audio...

The problem seems to occur no matter the file format. However, the same feature works on Blender 2.83.15.

The error message Blender gives upon the crash:

terminate called after throwing an instance of 'aud::FileException'
  what():  File couldn't be written, audio encoding failed with ffmpeg.
[1]    3363 abort (core dumped)  blender

And my Blender versions info are:

@neXyon Can you reproduce this issue? On Windows things seem to be working fine

I can reproduce with Blender 3.0.0 dfa3dcbab9.
No crash file is written and nothing out of the ordinary shows up in the debug log though, so I'll build a debug build to see if I can get a call stack.

Tested using:
OS: Windows-10-10.0.19041.630-SP0 64 Bits
GPU: GeForce GTX 470/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 391.35
CPU: i7-950 @3.07 GHz SSE2 SSE3 SSE41
RAM: 8.00 GB
