@s777ss You have a sound bug which you can tell by the SND/XACT warnings. Simple fix steps are:

Windows key > type: Control Panel > Open > Sound > Playback > select the Device you use: Configure > Stereo > finish configuration, Properties: Enhancements > Disable all enhancements, Advanced > 16 bit, 44100 Hz, Spatial Sound > Off, Restart or Shift+Shutdown (not just Shutdown) of PC

If your headphones come with any applet/program, then you may want to disable that & try using the headphones without it. Similarly, if they use a USB or Bluetooth dongle to connect to the PC, see if you can connect directly without the dongle.

See this thread for further troubleshooting: https://forum.faforever.com/topic/4084/solutions-for-snd-error-xact-invalid-arg-xact3dapply-failed

Also, I'd suggest that you go to FAF Client > top left menu > Settings > Forged Alliance Forever > Use FAF Debugger when starting Forged Alliance > ✔ > click "Get the latest version of the debugger". This will create a more detailed log to assist with future troubleshooting.
