somethings totally been wrong with my audio device. everytime i try to play music it shows me a message saying something like "there's no sound device or it may be in use by another program..etc.." i've tried almost everything. reinstalling.. troubleshooters.. etc. but still shows up to be the same problem. if anyone thinks they can help then pleaseeeee do.. i feel so helpless! oh and for some reason i have 3 audio codecs in the device manager under sound, video, ... is that ok? or does it have anything to do with the problem? well i'll really appreciate it if my problem solves.. its abt time. =] this is the error message i get on win media player: Windows Media Player cannot play the file because there is a problem with your sound device. There might not be a sound device installed on your computer, it might be in use by another program, or it might not be functioning properly. but i can still play videos just without any sound..
