Hi Marcellus,
This often happens with Real Trek drivers, first, disable the audio driver and uninstall it, Reinstall the driver and check for any updates.
Once done, select for which audio device to use, also, when you plug in headphones, does it detect the audio?
Is this issue just for the machine's speakers?
If the issue persists after the full driver reinstallation, let me know and we can troubleshoot further.
