The sound Galaxy Washington 16 sound card employs the Aztech Labs AZT2316-s Chipset. This driver will allow FULL DUPLEX operation under W95 and W98. This is in fact the latest driver from Aztech Labs for this Card and works well. However it was not easy to install, and I would suggest it is not for the faint hearted or inexperienced. I strongly advise that you go to Control Panel>System>Device Manager and print a summary of the resources in use on your machine before you start. This will enable you to correct the inevitable changes that will be made on your system by installing this driver. As I said, it does work, but make sure you know what you are doing before you start.
