Managing these drivers on vintage hardware often requires manual intervention: C-Media CMI8738/PCI (C3DX) - The Retro Web
If you have a modern PC and simply need sound, do not use an HSP56 card. Invest in a cheap USB Sound Card dongle . These cost less than $10, are plug-and-play, and provide superior audio quality without using legacy CPU resources. hsp56 sound card driver

The HSP56 (e.g., HSP56 MicroModem or PCI Audio) is a legacy software-based audio and modem combo chipset from the late 1990s, relying heavily on host signal processing (HSP). Unlike hardware-accelerated sound cards, the HSP56 offloads mixing, sample rate conversion, and effects to the CPU via a proprietary Windows driver. This paper examines the driver’s architecture, its reliance on the Windows Driver Model (WDM), the lack of open-source support, and methods for reverse engineering to enable functionality on modern operating systems. We present a case study of driver extraction, disassembly, and partial reimplementation using Linux ALSA. : These chips often provide both audio and

Vintage gaming enthusiasts use or 86Box to emulate an entire Pentium II or III system. These emulators virtualize a Sound Blaster 16, not an HSP56. You can run Windows 98 inside a VM and map the physical HSP56 card to the host – but the host must still have drivers. Instead, simply emulate a different sound card that has modern drivers (e.g., Sound Blaster 128).
If the driver is for an older version of Windows, you may need to run the installer in Compatibility Mode Common Troubleshooting Modem Conflicts
