Ok, that's nice to know, I had the same problem lately, after upgrading to
0.2.0-pre10p1. I supposed it was not a real problem, since things appeare
to work simply fine anyway. 
On the other hand, another thing came up that may be a real problem:
alsactl always complains with the message: 
"alsactl: MIXER switch read error (Device not configured) - skipping" 
This did not happen before, and does not seem to cause problems, but what
does it mean? I can use the mixer perfectly via alsamixer, so it does seem
to be actually working! 
	Last question, most important one, this definitely is a REAL
problem:  my computer is a laptop, an AcerNote Light 370PC with a Yamaha
OPL-SA3 embedded. When it goes in hibernation mode, saving its complete
status (memory, registers, whatever...) on disk, upon resuming it messes
up the alsa system. For example, if I try to play a sample with aplay it
gets played over and over until I break it. Stopping and restarting alsa
cures it, but it implies shutting down whatever may use sound, before,
e.g. the sound module of Afterstep, rplayd, etc. Would it be easy to
implement some way to reset the sound system without having to unload and
reload the modules?  This would do the trick.  
Now my config: Debian Linux 2.x ("unstable" distribution), kernel 2.0.36,
alsa modules 0.2.0-pre10p1, alsa library 0.1.3, alsa utils 0.0.8, modutils 
2.1.121.
