I had a new sound card installed along with Soundblaster software. Now my Rockwell standard k56 modem doesn't work. The system keeps detecter a 56K SpeakerPhone PCI modem and installing it. This doesn't work. I have tried uninstalling the speaker phone modem and reinstalling the standard modem. This doesn't seem to work. I get a message telling me to check my modem connection or turn it on and off. Any suggestions. The modem was moved from one slot to another but was not changed otherwise.
