#1: Creating the indicated file in the specified directory, with the 
specified content did not appear to change anything.  I double and 
triple checked the content.
#2: After installing, and even after rebooting, I did not get any 
sound.  Actually, if I turned the volume all the way up, I would get 
very faint (soft) sound.
I tried right-clicking on the speaker icon in the task-bar, and it 
yielded an old-style GUI, and it appeared the wrong sound-card was 
selected (the internal one, rather than the Soundblaster).  But my 
attempts to select the correct sound-card using the GUI were not 
successful.
In the past, the internal (ICH) sound-card is disabled in the BIOS 
setup, and it was not visible to the system, but it is visible now, 
despite not having changed the BIOS setup.
Changing the volume levels on the GUI also didn't fix anything.

The only thing that fixed it, was when I download PulseAudio and 
PavuControl, and in PavuControl, I selected the proper sound card. I 
learned this installing on my other (450 megahertz) machine.
Lubuntu uses ALSA (not PulseAudio) initially.  Once I changed over to 
PulseAudio, sound started working.  That was probably why sound started 
working on my other system after reboot.  I had also installed 
PulseAudio and PavuControl before rebooting.
