Sound Problems with ESS ES1688 AudioDrive

• Microsoft Windows operating system versions 3.1, 3.11
• Microsoft Windows for Workgroups versions 3.1, 3.11
• Microsoft Windows 95

SYMPTOMS

When you are using a computer with an ESS Technology ES1688 AudioDrive sound card, sound may not work correctly, or may cause programs to stop responding (hang). In Windows 95, Device Manager may report a problem with the device, or that the device is not working correctly.

CAUSE

The ESS AudioDrive device that exhibits this problem is an onboard chip that is soldered to the motherboard. Early versions of the driver for this device cannot reserve physical RAM, and allow the driver to be paged out of virtual memory. The device is not capable of using virtual memory.

Although Windows 95 correctly identifies the sound card as an ESS Technology ES1688 AudioDrive sound card, the Windows 95 driver does not work correctly.
