This setup has been running fine for years.

The day before yesterday, I switched from DSL to cable modem, and about the same time discovered that I no longer have sound (I like to listen to internet radio) and my volume icon has disappeared from the taskbar, even though the box is still checked in control panel/sounds and audio devices.

When I go to control panel/sounds and audio devices/sounds/program events and select a sound assigned to an event, I can't preview the sound; that button is grayed out. When I play an online game that uses Java, I still have sound and when I go to control panel/multi channel sound manager, I can conduct the speaker test successfully.

I just have no sound during normal system and program events. I don't think this can be modem change, but I just don't know. Any suggestions would be appreciated.

I already downloaded the Realtek audio driver, uninstalled and reinstalled it to no effect.

This is one of those situations where uninstalling the device in the Device Manager, then rebooting and letting Windows re-detect and re-install drivers for the device, may help.

Thanks for your suggestion. It made me think of using System Restore. I don't like to use System Restore because of a severe problem it caused for me several years ago, but I went back and l looked at my latest restore points to see what events had occurred around that time, and discovered that maybe a month before I experienced this problem, I had downloaded "360Amigo System Speedup" and installed it. I removed it from my computer and the problem disappeared. Your suggestion reminded me of this resource.
