i have created swap dll files .Then i registered this SwapAPO.dll file using regsvr32 command.I modified the regedit by including my custom swap APO.Then i restarted the system.Then i played a song in win amp.I choose left speaker.But i installed swapapo.dll,so the sound should be hear from right speaker.But music is playing from left speaker itself.which means audio driver is not taking my swapapo.dll custom file.Any suggestions to accomplish this,...
