[pulseaudio-discuss] how to direct the sound from an MPEG file to the external speakers

[PD Crone]

I have used OpenSuse for a while;

I have installed Linux Mint *on a separate computer* to investigate 
that; when I play a YouTube video on Firefox in Mint, the sound comes 
out of the external speakers; which I am happy with;

however in Mint, when I click on an MPEG file, and select MPlayer, the 
sound comes out of the small USB handset  that we use for VOIP;

when I load an MPEG in OpenSuse, and select MPlayer; the sound comes out 
of the external speakers on that different (separate) computer; but I 
don't think I ever determined that should happen; but I remain pleased 
it does!

  In both OpenSuse and Mint, I can locate the Pulseaudio Applet; and 
click on Manager;

and get options of Server information; Devices; Clients; Modules; Sample 
Cache

I would be very grateful if I could receive any advice on how to attempt 
to direct the sound from the MPEG files to the external speakers; the 
speakers are connected to the green sound out connection on the 
motherboard; (ie no separate sound card)
