"alsasound" is just a shell script that starts the driver.
it mostly just runs modprobe to load the appropriate kernel modules.
then it exits.
To see if alsa's running:
ls /proc/asound

If alsa's running, that directory will exist, and will contain
lots of informative files.  If alsa's not running, it will not exist.

Also, /sbin/lsmod should show you what modules are loaded.
Which ones depends on the soundcards you have.
Here's what I get when I start alsa on my laptop with a nm256 soundcard:

$ /sbin/lsmod                  
Module                  Size  Used by    Not tainted
snd-nm256              57892   0
snd-ac97-codec         23984   0 [snd-nm256]
snd-pcm                53216   0 [snd-nm256]
snd-timer               9280   0 [snd-pcm]
snd                    23208   0 [snd-nm256 snd-ac97-codec snd-pcm snd-timer]
