No you do not. XMMS can use "audio out" (ie plug the CDROM Audio cable into 
the soundcard) or DAE (Digital audio extraction), where it reads the cdrom 
drive as if its raw data, and does the conversion to sound in software. This 
results in the "audio over bus" that the original poster pointed out.

To do this. you need to install an xmms-plugin (they did not come with my xmms 
version). There are two of them  in portage to my knowledge:

"AudioCD Reader" : libcdread.so
"CD Audio Player" : libcdaudio.so

Out of the two, I use CD Audio Player, because it has more features, such as 
Multiple CD-ROM support. This allows me to plugin in external CD-ROM's (such 
as USB CD-ROMS, and SCSI CD-ROMs/CD changers) and use them to play audio CD's
 
Note that in both drivers, you need to state you want to use  DAE rather then 
the old analog method (this is due to the fact that not all CD-ROM's have 
good DAE capabilities). Under "CD Audio Player", you need to set "Play mode" 
to "Digital audio extraction", along with configuring/checking your drive.

In portage they are called:

"media-plugins/xmms-cdaudio"  => "CD Audio Player"
and
"media-plugins/xmms-cdread" => "AudioCD Reader"

emerge one of them, restart xmms, and you're set ;)


Happy listening!
