On my Dell Dimension 4300 XPSP2, my audio output (and CD playing ability) suddenly stopped working--and I did not make any changes to my machine, did not install any software or hardwarew, etc. .
I've been using a SoundBlaster Audigy SE board for about 18 months, and I have "system sounds", like the tune you hear when Windows boots up, error sounds, etc. But there's no volume control showing on my tool bar on the bottom of my screen, and when I click Control Panel | System | Hardware | Device Manager, under Sound, Video and Game Controllers, Sound Blaster audigy is listed.
However, when I click on Control Panel | Sounds and audio Devices, a box comes up labelled "Sounds and Audio Devices Properties", and under the Volume Tab, that box says "No audio device." And under the Audio tab, the Sound Playback section shows "no playback devices" under Default Device. Same with the Sound Recording section ("No recording deviices")--and there's nothing I can check to install these devices.
Also, when I click on the Volume Control icon on my desktop, a box pops up saying "There are no active mixer devices available. To Install mixer devices, go to Control Panel, click Printers and Other Hardware, and then click Add Hardware."
But Control Panel does not show a heading "Printers and other Hardware." The closest tab I can find is "Printers and Faxes", but it has no option to add hardware. Nor does Sounds and Audio Devices have any option to add hardware.
I was a programmer years ago, so I have some knowledge of systems "in general", and to me this looks suspiciously like one problem that somehow propagated and caused the others.
I'm reasonably skilled at installing hardware and software, and not hesitant about playing with innards, but this has me puzzled.
Anyone have any knowledge of this stuff? Any ideas about what might be the problem?
