Description
### System Information
Fedora Linux Asahi Remix 42 (Forty Two [Adams]) aarch64, Apple MacBook Pro (16-inch, M1 Pro, 2021)
### LMMS Version(s)
1.2.2-17.fc42
### Most Recent Working Version
_No response_
### Bug Summary
While LMMS recognizes that sounds are being played, it is not sending the audio to the operating system to be played by the speakers (the desktop icon does not have the usual icon to indicate the app is playing a sound).
### Expected Behaviour
The desktop should recognize that LMMS is playing sounds.
### Steps To Reproduce
Download lmms-1.2.2-17.fc42.aarch64 using dnf on Fedora Linux Asahi Remix and attempt to play a sound.

Research direction
No source file or test is named. Start by reproducing playback with lmms-1.2.2-17.fc42 on Fedora Linux Asahi Remix and inspect the reported library-loading and LADSPA errors alongside CPU usage. Done means LMMS sends audio to the operating system and playback is recognized by the desktop without the reported excessive CPU usage.
