Driver — Hsp56 Sound Card

Before downloading a driver, you need to identify the exact vendor and device ID of your chip. Open the on your vintage Windows PC.

If you tell me the exact model number or post the hardware IDs from Device Manager, I can search for a more specific driver and provide direct download suggestions.

HSP56 cards are notoriously bad with DOS games. Because the CPU does the mixing, DOS real-mode drivers are huge and buggy. However, many C-Media based HSP56 cards support via a TSR.

The HSP56 is a legacy Host Signal Processing modem, not a standalone sound card. Successfully using it requires: hsp56 sound card driver

If the HSP56 driver is missing or corrupted, you may encounter: No sound/audio output.
