i recently added winxp pro to my existing win2k setup (dual boot/separate drives). love it...but...somethings just don't seem to be working on it. for example, i can't hear any sound alerts from my yahoo messenger, can't use the audio tuning wizard and can't hear anything on voice chat. i have a soundblaster 5.1 live! sound card which is working fine. yahoo!'s problems don't occur in win2k where i hear the familiar door slams and other alerts as well as being able to talk on it. my other question is..is it a fact that i won't be able to talk (use voice chat) on windows msn with users who don't have winxp? is there any workaround for both of these problems? would really appreciate any advice. have been searching newsgroups and forums for anything but haven't found a clue yet.
