@rdfg 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.
