Oops, let me put this back on this list. Didn't check the address...
You mean does -ao pcm use hw:0? No, it should not touch the sound
card. It should only dump to a file. I am not sure if the same is true
for the --dumpaudio option (which is what I usually use to create a
file from a stream). That may dump to a file and touch the sound card
(and thus fail if the card is held open).

Oh, wow, that is some fancy audio. With stuff like that, do you
usually just run JACK?

So for you the stream is failing, if not quite immediately. It gets
the header at least...
You could try increasing the -cache as it says. Not sure what else. My
mplayer is mplayer2 from sid, btw
