Finding a driver for the "HSP56" can be confusing because it refers to a specific type of "Host Software Processed" chipset often used for combined modem and sound card functions
. To get the right driver, you first need to identify which manufacturer’s version of the HSP56 you have, as different companies (like C-Media, PCtel, or SiS) used this branding for their hardware. Common Drivers by Manufacturer
Most HSP56 devices are based on one of the following chipsets. Check your hardware for these names: C-Media (C3DX HSP56 / CMI8738)
This is one of the most common versions found on PCI sound cards. You can often use the standard CMI8738 audio drivers for the sound portion of these cards. Find these on the C-Media Download Center The Retro Web PCtel (HSP56 MR)
Primarily known as a "MicroModem," these often appeared as integrated components on older motherboards.
Drivers for various versions (v2.41, v2.30) are hosted on databases like SiS / Motorola (SiS HSP56 MR)
These were frequently used in laptops and budget desktop systems. Hardware IDs for these typically start with PCI\VEN_1039&DEV_7013
. Drivers for Windows versions ranging from XP to 10/11 can be found on sites like How to Identify Your Specific Card
If you aren't sure which one you have, the most reliable way to find the correct link is by checking the Hardware ID Device Manager on your computer.
Right-click the "Unknown Device" or "Multimedia Audio Controller." Properties Hardware Ids from the dropdown menu.
Search for the "VEN" (Vendor) and "DEV" (Device) numbers online (e.g., is C-Media). HSP56 MR Drivers Download for Windows 10, 8.1, 7, Vista, XP
The HSP56 typically refers to a host signal processing (HSP) modem and audio chipset often found in legacy systems, frequently branded under C-Media, SiS, or Motorola. Because these are legacy components, finding modern drivers can be difficult, as many only officially support versions up to Windows XP or Vista. 1. Identifying Your Hardware
Before downloading, you must confirm which manufacturer (vendor) produced your specific HSP56 card. Common vendors include: C-Media ( C3DX HSP56 ): Often used in budget PCI sound cards.
SiS (Silicon Integrated Systems): Often integrated on motherboards.
Motorola: Frequently associated with the modem part of these "combo" cards. To find your specific hardware ID in Windows: Press Windows + R, type devmgmt.msc, and press Enter. Expand Sound, video and game controllers. Warning: You may need to create a free
Right-click your device, select Properties, go to the Details tab, and select Hardware Ids from the dropdown. Look for a string like PCI\VEN_1039&DEV_7013. 2. Common Driver Sources C-Media: Drivers for the audio portion (often the
chip) can sometimes be found at The Retro Web or the C-Media Download Center.
SiS/Motorola: Aggregator sites like DriverScape and DriverHub
host various legacy versions (e.g., v6.12.25.05). Use caution with third-party sites and always scan downloads for malware. Manufacturer Support: If you have an device, Solvusoft provides manual update guides. 3. Installation & Troubleshooting Guide

The HSP56 is a legacy hardware component, often found as a combination modem and sound card chip, typically powered by the C-Media CMI8738
chipset. Finding reliable drivers for modern systems like Windows 10 or 11 can be difficult because the hardware is considered "vintage". Direct Driver Download Links
You can find drivers for various versions of the HSP56 (including MR and Micromodem variants) through these specialized driver repositories: HSP56 MR Drivers (Multi-OS) DriverScape - HSP56 MR provides versions for Windows 10, 8.1, 7, and XP. C-Media CMI8738/PCI-SX (Audio Component) : Since many HSP56 cards use this chip, the C-Media CMI8738 Drivers are often the most compatible for audio functionality. HSP56 Micromodem : Specific modem-side drivers can be found at DriverScape - Micromodem Intel/SiS HSP56 MR Variants
: If your card is integrated with an Intel or SiS chipset, specialized drivers are available at DriverHub - Intel HSP56 MR DriverHub - SiS HSP56 MR Brief Overview: The HSP56 Sound Card
The HSP56 (Host Signal Processing 56K) was a popular low-cost solution in the late 1990s and early 2000s. Unlike high-end cards that have dedicated processors, "host-based" cards like the HSP56 rely on the computer's CPU to process audio and modem signals. Chipset Heritage : Most HSP56 cards use the C-Media CMI8738/PCI-SX
audio processor, which supports up to 5.1 channel surround sound. Hybrid Functionality
: It is often a "combination chip," meaning it handles both modem communications (56K) and audio playback. In some BIOS settings, the modem part can be deactivated to avoid conflicts. Legacy Support : It includes support for older standards like SBPro (Sound Blaster Pro)
emulation for DOS-based games and includes a MIDI/Game port for vintage joysticks. Compatibility and Installation Tips HSP56 MR Drivers Download for Windows 10, 8.1, 7, Vista, XP
