Installed Ubuntu 12.04 on a new (used) computer for wife, pretty much duplicating what I have on my own computer. Both are 64 bit: mine AMD, hers Intel both about 4 years old. I set up Firefox for her with the same 5 plugins as mine, including WMP Plug-in 10 (compatible; Totem). When I go to an internet radio station on my computer and click on the play button (it says for WMP), the WMP plug-in pops up and I get both audio and a streaming light show. It has worked this way for me with very little interaction on my part for about 5 years. But I can't get it to work that way for her computer. The WMP pops up with the start of a graphic on the screen (a blob of blue-can't make out what) and it freezes. No video, no audio. Nada. The station is KHSU.org and the URL for the streamer shows asx, which I take to mean it's ASF content. I've tried every suggestion on Firefox help, but nothing works. Have loaded the Ubuntu restricted extras library, but still no go. I can play the station with Ubuntu's Movie Player and Rhythmbox, but it's cumbersome. What could be causing the difference between two nearly identical (other than hardware) computers? Setting mine up to play audio thru WMP was almost automatic with almost nothing to tweak on my part.
