The term refers to Host Signal Processing technology, designed to handle 56k modem data. In many late-90s and early-2000s systems, companies like C-Media , SiS , and Motorola integrated this modem functionality with basic audio features on a single PCI card or motherboard chip.
Because official manufacturer sites no longer host these files, you must rely on trusted legacy driver archives (such as DriverGuide or the Internet Archive).
After installation, restart your computer. In Device Manager, the device should no longer have a yellow exclamation mark and should appear under the category.
