A problem has cropped up on one of my winxp machines where MP3 files that are either linked or the URL directly pasted into the address bar seem to play but there is no audio output. The playback gadget does show that the file is being played, and the file does get transferred OK. This happens in both Chrome and Firefox.
I've updated Java and flash player in an attempt to fix the problem, no change. YouTube videos play with no problem. A downloaded mp3 file does play when loaded into both Windows Media Player and Winamp.
