On the Sound tab of Sound and Audio Devices Properties, my Default Device says ‘Modem #1 Line Playback’ and is my only drop down choice. I made no configuration changes or installed any new software, it just stopped working.
I have googled for solutions, to no avail. I have an ‘!’ next to the Microsoft Kernel Audio Mixer in Device Manager that upon re-install displays a message that there was a problem installing this hardware(MEDIA) I/O operation has been aborted because of either a threadd exit or an application request(both installing from driver folder and recovery CD).
I don’t particularly care what sound device I have, just one that works again. I’ve uninstalled the sound devices and let them re-install on reboot and have checked the BIOS settings(I don’t have any sound related settings there).
In Admin Tools > Services ‘Windows Audio’ is started and set to Automatic. When I manually try to play a windows sound in the Sounds tab I get an error message that says my sound card may be in use.
Under Sound and Audio Devices in Device Manager I currently have(when I ‘Show Hidden’):
-Legacy Audio Drivers
-Legacy Video Capture Devices
-Media Control Devices
-Microsoft Kernel DRM Audio Descrambler
-Microsoft Kernel System Audio Device
-Microsoft WINMM WDM Audio Compatibility Driver
-RealTek AC’97 Audio for VIA ® Audio Controller
-Uni-modem Half-Duplex Audio Device
-Unknown Device(which is the Microsoft Kernel Audio Mixer which won’t install) (!)
Don't know what else to try. Any help would be appreciated.
