Tried to load the nxaudio.kext (5.0.43) on latest OSX failed with the following message, thus no audio redirect available:
# kextutil /System/Library/Extensions/nxaudio.kext
Diagnostics for /System/Library/Extensions/nxaudio.kext:
Code Signing Failure: not code signed
Untrusted kexts are not allowed
ERROR: invalid signature for com.nomachine.driver.nxau, will not load

2)
system_profiler SPSoftwareDataType
3)
codesign -vvv /System/Library/Extensions/nxaudio.kext/
4)
find /System/Library/Extensions/nxaudio.kext/ -type f -exec md5 {} \;

Unfortunately it’s a bug. It’ll be fixed in a next release.
Old kext wasn’t replaced during update.As a workaround you can do this:
1. Uninstall NoMachine:
sudo rm -rf /Applications/NoMachine.app
2. Install again the newest package.

It works, thank you.
