lack of sound, can't install driver

I updated from Kubuntu 6.10 to 7.1 and haven't been able to get sound. (Idid
have it in 6.10). I still have no sound. I went to UBUNTU documentation, sound
troubleshooting. Following their instructions, I
found out that snd-emu10k1x for my Dell Soundblaster Live Value wasn't installed
(instead Kinfocenter shows sound: 3.8.1a-980706); Kubuntu 6.10 from which I
updated did have it and the sound was OK. I tried to install emu10k1x using
Alsa-source; module-assistance wasn't found; I had to downloaded it, along with
alsa-source, going to system-adept manager; the shell command still did not find
module-assistance even when I copied it to the same directory I was issuing the
command, so I couldn't use it. Using "dpkg reconfigure alsa-source" I was
finally able to install emu10k1x. lspci shows the card; see the first blocks in
the attached file. However, I cannot load it with modprobe because as you will
see in the attached file, modprobe calls for /sound/core...and it should be
/sound/acore (Acore) where the needed files are. Also please notice that at the
end there is an Error, inserting snd_ac97_codec; in
Konqueror, I do see sound/pci/ac97/snd-ac97-codec.ko, codec.ko being a binary
file; how can the error be corrected?
Please check, as it is this SB Live is troublesome, and advise me what to do.
