Audio Output From MPlayer ?
Just recently downloaded and installed MPlayer, I installed the win32 codecs as I want
to play some WMA files that I've recently downloaded however when I attempt
to play the WMA file, there does not appear to be any sound ?
configure options when building MPlayer :
./configure --enable-gui --enable-divx3linux --enable-libavcodec --enable-vorbis --enable-mp3lib --enable-liba52 --enable-alsa --enable-ossaudio --enable-runtime-cpudetection --enable-win32 --with-win32libdir=/usr/lib/codecs/win32/ --prefix=/usr
It built and installed fine however when I attempt to play a WMA file I get the following :
$ mplayer Back_To_School.wma

From above output, it seems to locate the correct win32 codec, and process the file for 4.44 M/SS, however there is no audible sound.... any idea why ?

Try the raw file writer audio output plugin to try and see if the fault is in the actual audio output or in the audio decoding. Something like "mplayer -ao raw -aofile audio-output file.wma" if I recall correctly.
Then, do a hexdump of it ("od -t x2 audio-output") and see if the samples differ much or if they're pretty much the same. If they're very equal, it's "supposed" to be silent, or in other words, the fault is in the audio decoding. If they differ much, sound is supposed to come out of your speakers, or in other words, the audio output is somehow broken.
