That's the problem. Your stream have no video (that's ok, it's audio  
only), MPlayer was not able to play audio (decoding was ok with  
liba52), so it had nothing to do and quit.

If your problem is with audio device, you should get it with every  
file. Can you confirm it?
Looks like you're using Alsa (i use oss and everything works ok here):  
can you try oss emulation mode? (if it works, it can be a workaround)
Else, if you have some time to spare, try to downgrade ao_alsa1x.c  
(since you're using Alsa 1.0.2) using cvs upgrade -r # libao2/alsa1x.c  
where # is the version number of the file (current version is 1.43),  
and check when it broke.

I'm not an Alsa user, maybe someone else can give you more useful
