Thanks for reminding me to test this feature. In xemacs (*), it works
nicely allowing playback of any media i've thrown at it.... Using
dired, find the desired file and use keyboard command '!'
(shell command on files), giving "gst123" as the command. The file
will play but will do so in the foreground. To stop it, issue a C-g .
The *Shell-Command-Output-Buffer* will contain the following (while
playing audio track for http://www.youtube.com/watch?v=AI8NuFAETMQ ).

You can multiple select files as well and then issue command '!' and
it should play through the list of selected media.

However, since it plays in the foreground and makes emacs
unresponsive, you could also start it in the background through a
script and tell it to be less verbose, set desired audio interface,

Note that it'll playback web clips from the command-line too. With
ALSA setup per

mobo's SPDIF out at 48k):
