I had this same problem about a week ago, and i'm pretty sure i fixed it by just doing a system restore, so i tried that and now opera 9.5 works, but firefox 3 does not, and still no music.
I've tried closing media monkey (through task manager-won't close on it's own when trying to play music) and restarting mm, and every once in a while there will be a ffdshow popup asking me if i want to use ffdshow or not i've tried yes and no with no success. So then i tried to uninstall ffdshow but it gives me message: "File 'C:\program files\ffdshow\unins000.dat' does not exist. cannot uninstall". I also tried to uninstall a different program, orbit download manager, and got the same message. But another program, malwarebytes' anti-malware, was able to uninstall.
Also, there are no problems in the device manager, and my computer can play windows sounds (that annoying beep). Also, through opera, i can't hear sound. videos play without music, myspace appers to play song, but i don't hear any thing. And when i go to a radio station's website, the window that plays their radio station fails to load.
I have a dell dimension e510, xp pro sp2, 1 gb ram, intel 8280 1gb ICH7-high definiton audo controller, and dell DM051 motherboard (via everest)
