I have a workstation here that is a Dell OptiPlex 170L. The user called my and said no sound. I go to check things out. She wasn't lying. No sound. The first thing I noticed from "Sound and Audio Devices Propterties" is that "Use only default devices" is checked and that the the selections for "MIDI music playback" and "Voice playback" are left empty. I proceed to uncheck the box for "Use only default devices" and fill in selections for each of the other two items. You would think that would work. I click Apply and then OK. Still nothing. I go back in and check to see what's going on and it's in the same state it was before I sat down ("Use only default devices" is checked and "MIDI music playback" and "Voice playback" are empty). So I uninstall the drivers (SoundMAX) and reboot. I reinstall the drivers and the same thing happens. I opened up the case and checked all the wiring out (all good on that front). It doesn't matter what I try to get the settings to stay, they won't. I am unable to play the sounds from "Sound and Audio Devices Propterties", Sounds tab. Any ideas?
