Description

### System Information

Ubuntu 22.04

### LMMS Version(s)

1.2.2, master at bda042e1e

### Bug Summary

Vibed has issues exporting at 192 kHz.

### Expected Behaviour

It exports at 192 kHz all the time?

### Steps To Reproduce

Export [VibedExport.mmp.txt](https://github.com/LMMS/lmms/files/15081304/VibedExport.mmp.txt) at 192 kHz! (remove .txt)
Observe the curve (see image).
Export the project again but adjust the knob Length (string length) to 2.
The exported soundfile now looks like expected.

The steps above was done with fpe debugging flags set so no floating point errors detected.

Research direction

Start with the attached VibedExport.mmp project and reproduce the export at 192 kHz on Ubuntu 22.04, comparing the output with the string-length knob set to its default and to 2. Investigate the Vibed export path; done means the 192 kHz export produces the expected curve without requiring the length adjustment.
