I need sound drivers for a sound card that gives a message "soundcard sc-003" and it has the following "serial number 051020404."
The best way to find out which sound card you have is to use a software that handles these problems very well and in particular one does its job accordingly. Unknown Device Identifier scans your devices for PCI/VEN strings and based on the results it searches an online database to match the results. The results are accurate and the drivers provided or sugestions to drivers are known to work in most of the cases.
