Description
### System Information
NixOS 26.5
### LMMS Version(s)
LMMS 1.3.0-alpha
### Most Recent Working Version
from 25.11, sorry cannot really tell what exactly
### Bug Summary
Just updated lmms to play fresh sequence, trying to get it working, my old theme got reset and sound is broken, it shows playback in pwvucontrol with no bar being filled, cannot hear any instruments including default triple oscillator :/
BTW: I tried both Alsa and pules audio interfaces in setting, no success. Anything else works on my machine. Both llm audio modes gimme interfaces in pipe, no sound tho
How can I help ?
### Expected Behaviour
Sound working well
### Steps To Reproduce
Nixos 26.5
nix-shell -p lmms
### Logs
Logs are spamming with
```
fluidsynth: warning: No preset found on channel 7 [bank=0 prog=0]
```
No much useful info.
Tho the github template did not give me any flags to get more verbose evidence

Research direction
Start by reproducing the issue with `nix-shell -p lmms` on NixOS 26.5, then compare LMMS playback with pwvucontrol while checking the reported FluidSynth warnings. Done means identifying why playback produces no audible output and confirming that instruments play through the selected audio interface.
