  	   Sorry!  This is my first report of a bug in 10 years
	   of running Debian.

  	 I don't understand this line.  Can you be more specific?

       	    I have just done this.  But I don't understand the
	    relationship between ALSA and pulseaudio.  Are they
	    competitors? supposed to work together?

	    The result:
Linux version 3.2.0-4-686-pae (debian-kernel at lists.debian.org) (gcc version 4.6.3 (Debian 4.6.3-14) ) #1 SMP Debian 3.2.57-3

     	    Did you mean Lenny?  thats Debian 5, no?  I have just
	    installed Wheezy, although Squeeze was working very well.

	  Haven't I/we established that my problem is a configuration
	  issue?  My speakers are what they've always been; my
	  hardware, three weeks old, works fine when booted from a
	  M$ DVD.  So I am hoping that advice from experts will
	  help me to get as good sound results with Wheezy as I
	  had with Squeeze.

Again I thank you for your quick response.  Now that I'm addressing
768383 at bugs.debian.org as well, maybe others will have a suggestion.
