Thanks for the reply. Is there any other explanation? This machine is a 
server with no other audio-using applications on it, and ps -aux shows 
nothing with any sound access. Ices logs that it opened the sound device ok:
[2005-05-02  10:11:19] INFO input-alsa/alsa_open_module Opened audio 
device hw:0,0
[2005-05-02  10:11:19] INFO input-alsa/alsa_open_module using 2 
channel(s), 44100 Hz, buffer 371 ms (2 periods)
[2005-05-02  10:11:19] INFO stream/ices_instance_stream Connected to 
server: localhost:8000/stream.ogg
[2005-05-02  10:11:19] INFO signals/signal_usr1_handler Metadata update 

I'd also expect that sound system blocking would prevent rec -s w -c 2 
-r 44100 test.wav from working.

I can certainly give it a try, but I don't see why it would make a

ok, that's just active during debugging anyway.
