First, a critical clarification: The HSP56 is NOT primarily a sound card. It is a PCI modem chip (commonly the Conexant/Rockwell HSP56 MR or SmartHDA series). However, many OEM computers (e.g., older Dells, HPs, Compaqs) bundled this modem on a combination card or motherboard that also included basic audio (AC'97 or HD Audio).

If you are looking for an "HSP56 sound card driver," you likely have one of these situations:

Vintage gaming enthusiasts use PCem 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).


The HSP56 typically refers to a host signal processing (HSP) chipset used in older 56K PCI modems and integrated sound/modem "combo" cards, often associated with vendors like C-Media (CMI8738), PCTel, or SiS. Because these are legacy devices, modern operating systems like Windows 10 or 11 do not support them natively.

If you are looking for drivers to get this hardware running on older systems, you can find them through the following resources: Driver Download Sources

DriverScape: Provides archived HSP56 MR drivers for Windows XP, Vista, 7, 8, and 10.

DriverHub: Offers SiS HSP56 MR driver packages intended to restore sound card functionality on various Windows versions.

, particularly for hobbyists setting up Windows 98SE or early XP "retro" gaming rigs with C-Media CMI8738 Go to product viewer dialog for this item. cards. Troubleshooting Tips

Identify the Chipset: The "HSP56" label is often generic. Use a tool like Everest Home Edition or HWiNFO to find the specific PCI vendor and device ID (e.g., PCI\VEN_1039&DEV_7013).

Windows 10/11 Compatibility: Most HSP56 devices rely on software-based processing that is incompatible with 64-bit modern Windows architecture. If a 64-bit driver is not available, you may need to use a Virtual Machine running Windows XP to access the hardware.

Driver Utilities: For automated detection, tools like DriverDoc can scan your system to match the legacy hardware with its database of over 2 million drivers.
