&gt; I literally can&#x27;t use my headphones without special OEM or Realtek software (forgot which) on Windows, and I can&#x27;t use them at all on Linux because there&#x27;s no equivalent.<p>If the problem is no output at all, it may be just a matter of toggling some HDA codec GPIO or EAPD pin to power up external amplifier chip, which can be done with <i>hda-analyzer</i>. But if it&#x27;s some combo headphone&#x2F;mic jack and detection doesn&#x27;t work then I have no idea.
