I was wondering if anyone can help me out. I get sound perfectly when playing a DVD, however, I don't get any sound when trying to play an mpeg or listen to the radio online using mplayer or mplayer-plugin. Does anyone have any ideas how to fix this? Thanks in advance.

This is what I get:

win32 libquicktime loader (c) Sascha Sommer

How did you install mplayer? Also, have to tried playing the movie in a different media player, like vlc?

Where did this QuickTime Audio decoder come from? It seems to be having problems. What format is the radio audio supposed to be in? If RA, you'd need the RealPlayer codec, if WMA, you'd need the Windows codecs, etc. Maybe QuickTime is trying to play these files (since QT generally thinks it can, despite the fact that I at least have rarely seen it succeed) but is in fact unable to, and .... you don't have the other necessary possiblilities installed, perhaps?

If this is the case, swing by and pick up some more codecs.

Actually I got it working. Thanks for your help. I had tried downloading the package from and installing it. However, I wasn't getting any sound out of mplayer. I went and downloaded the source and compiled it myself. Prior to compiling it, I went and extracted the codecs from the mplayer site to /usr/local/lib/win32. To configure mplayer I entered
./configure --enable-win32 --enable-gui
make install

Now all works great!
