From: My Own Private Hell
2) I've currently got 218 mp3 tracks (1.95Gb) in my customisation and have not noticed any lag on my oldish laptop. I do have the distinct impression that some of the tracks never play, and some play infuriatingly often. Might try Darkspire's advice to try and eradicate the strange stoppages of music I get sometimes though.
Believe it or not, I know how to fix this... though I am not 100% sure of the root cause...
When you enter a zone in the game that has a sound effect attached, the music is paused.
I have found to correct it that I must zoom in 100% as close as I can and well away from a zone that has a sound effect, and then unzoom. This seems to unpause the music
Never had that happen, I don't play with the story events on,maybe that is where that comes from? I was on about the diplomacy mood music, it sometimes used to forget to play the theme soundtrack again when you clicked 'goodbye', you had to go into diplomacy, select a race then click 'goodbye' again to get it to continue playing the track.
