You have a sound bug which you can tell by the SND/XACT warnings. You should go to Windows key > Control Panel > Sound > Playback > select the Device you use > Configure to ensure that your sound device is set to Stereo then look in Properties to make sure that all Enhancements & Spatial Sound are Off. After you've verified those settings, usually a simple Restart or Shift+Shutdown (not just Shutdown) of your PC will resolve the sound issue.

If that doesn't work, then you can have a look at this thread for further troubleshooting: https://forum.faforever.com/topic/4084/solutions-for-snd-error-xact-invalid-arg-xact3dapply-failed
