Hi, been having the same problem recently , have tried most of the things listed on the last couple pages of this thread, all to no avail. In the Sounds and audio devices properties under the audio tabs there are no defaults listed at all. I'm at a loss as to what to do Please Help!!
P.S. My machine is A compaq Presario 6000 model 6027US
I have Soundmax as my audio device and all my devices are shown to be working properly
