BTW, Spy Hunter's sound buzzing is often associated with power supply
issues, rather than the sound card. If one of the two large
transistors, amp chip, or caps begins failing, it will result in
buzzing. In fact, I just restored one that had this exact problem. PS
repair kits are inexpensive at Bob Roberts, or how can buy a switcher &
plug& play adapter replacement at Steven's ArcadeShop.
