I have set up the sb audigy gamer card for others with MJ on their systems.
try this... go to "settings" then chose "options" then find the "playback" tab.
under the "output" area there is a "device" named. usually the "wavemapper" works fine, but if you left click the down arrow you will also see your sound card listed in the drop down. try left clicking your sound card and then click the radio button. remember to shut down MJ and then restart it. See if this makes a difference. if it does, you need to acquaint yourself better with your sound cards setup through "Control Panel" of windows...
once you get that right, wavemapper (in the MJ settings) will be much better for playing under MJ as windows (and MJ) will know exactly what you want.
these guys at MJ can only do so much for "all" users, the rest is up to us.
Hope this helps...
remember MJ is trying to (and is) making a music solution for a myriadic complexity of machine diversities. (that sentence cost me $23 at the book store)
