Mpeg2 Layer 3 compressed sound files come in mono, joint stereo,
and stereo formats - that is a maximum of 2 sound channels, left
and right. Thus there are no center or rear channels sources to play,
so you would not hear 5.1 sound. And since they are only stereo sound
files, xmms and all the other players are only created to process two
channels left and right.
So even if your sound card was fully supported for 5.1 channels, why would you expect to hear 5.1 sound from an MP3, or even sound from the center speaker, when there is only left and right channels available?
Where you will find 5.1 encoded sound files are the AOBs on a DVD.
And there is actually one application which can process all 6 channels
and pass the sound over to a device with 6 channels supported, and that is mplayer
Change the number of playback channels, defaults to '2' if not
specified. If the number of output channels is bigger than the
number of input channels empty channels are inserted (unless
mixing from mono to stereo, then the mono channel is repeated in
both output channels). If the number of output channels is
smaller than the number of input channels, results depend on the
audio decoder (-afm). MPlayer asks the decoder to decode the
audio into as many channels as specified. Now it's up to the
decoder to fulfill the requirement. If the decoder outputs more
channels than requested, the exceeding channels are truncated.
This is usually only important when playing videos with AC3 au-
dio (like DVDs). In that case liba52 does the decoding by de-
fault and correctly downmixes the audio into the requested num-
ber of channels.
This option is honored by codecs (AC3 only) filters (surround)
and ao drivers (OSS at least).
Available options are:
6 Full 5.1
2) Being new to linux, I really don't which one to use. Ive been trying to use Xmms recently but the default seems to be Kaboodle so I used that at first.
Default? I have not heard of Kaboodle. The default on your system is in effect what has been made available and set by your distributor.
That's another thing about linux, I still trying to figure out how to set defaults for programs applications [/B]
I think perhaps you are using the wrong terminology here. Defaults, in particular X11 application default resources, are settings which provide the default colors and fonts for X11 Xaw and motif programs. What you are probably meaning, is how does one change the application fired up when you hit a menu item on the desktop menu.
This is either done with a GUI menu editor program or through direct editing of the menu file.
Usually the GUI menu editor is invoked by holding down the right mouse button on the menu and selecting preferences/edit properties item.
A dialog box then appears with settings for icons, path to executable etc, name of menu item, and one then just changes the path to that of the desired executable (assuming of course it is installed on the system).
There was once a joke item comparing Operating Systems to airplanes. In the case of Unix/Linux the analogy was that there was a group of people on the runway with a load of parts, wings, wheels, etc and they were all arguing about which parts they should use and what colors to paint them.
