I, too, am having a similar problem. After upgrading from Win95 to Win98 on a Compaq Presario system, I have no interactive volume controls available. I do have sound from the powered external attached PC speakers when I play a music CD, but otherwise, no sound from anything else. No Windows sounds from the internal PC speaker, either, when the external speakers are unplugged. The couple of music software composition packages I have loaded on the system (Band-In-A-Box, etc)will produce no soud, either. They start up OK and appear to be running, but no sound is produced. Any suggestions would be greatly appreciated. Thanks.
