Tested (Windows 98SE). Perfect condition. Perfect sound
 
PCI Sound Cards with the ESS ES1938S Solo-1 Chip, are average for Windows Gaming, but excellent for MS-DOS Games compatibility.

Under Windows you get a standard Direct Sound device, but nothing special. There is no dedicated control panel and no indication as to any EAX or A3D API compatibility. The Sound Card does make the ESFM available to Windows, this is an enhanced (compared to YAMAHA OPL3) FM and can make listening to MIDI files interesting.

The real highlight however is MS-DOS compatibility. The drivers do not require EMS memory, which helps to increase compatibility with games. I found that this card is amongst the very best in terms of playing DOS games and it's almost as good as an ISA based ESS Sound Card.
