You can try some utilities like SiSoft Sandra and the like. If the information is stored in a loacation that the utility probes, it will sometimes report the manufacturer and sometimes model number of the mainboard. You also might see if it can identify the sound chip installed onto the mainboard. This information can be helpful in that you can visit the website of the chipset manufacturer and often download generic drivers that may not be as feature-rich as the Sony ones, but will give you the ability to use the sound device.
