That command produces no output.

I have installed alsa-source.  Although it isn't mentioned in the 
README.debian, the module-assistant package came along with it.  I 
need to RTFM some more, and then I will try compiling the newer 
drivers.

Should it be reported as a bug against the 2.6.26 kernel package 
that it uses out-of-date alsa drivers?

Let me add some information just as background.  Sound was working 
with the 2.6.22 kernel before Lenny became stable.  My sources.list 
includes only testing.  The only system software changes since then 
have been the regular updates to testing.  I don't use sound 
regularly on that machine, so I don't know just when sound stopped 
working.  After I noticed the lack of sound, I installed the 2.6.26 
kernel, which changed nothing.  The only changes from Lenny that 
strike me as possibly relevant are the alsa packages and udev.  So 
somewhere in a simple upgrade process something gets broken, but I 
don't know what.  (I'm inclined to suspect udev, but only because I 
don't understand udev at all.)

Many thanks for your help.  I will let you know of any further 
progress (or lack of it).
