No sound

I am trying to make sure everything still works on my Slackware system since a recent snaffu on my part. So far, everything does except my sound seems to have disappeared. I didn't know how to manually restart the sound service, so I turned the executable bit on for /etc/rc.d/rc.alsa. I tried to restart it, and:
Code:
root@caitlyn:~# /etc/rc.d/rc.alsa start
Setting default ALSA mixer settings.
Storing default ALSA mixer settings:  /usr/sbin/alsactl store
/usr/sbin/alsactl: save_state:1595: No soundcards found...

So I should have sound, yet I don't. Videos don't seem to be working either. Also, I tried to install rosegarden through sbopkg and one of the dependencies needed ladspa_sdk, so I attempted to install that, but it gets to a point then just stops.
Code:
root@caitlyn:~# sbopkg -i ladspa_sdk

I don't know if the ladspa_sdk and video problems provide useful clues, but I have a feeling that they'll clear up once this sound issue is resolved. Thanks in advance to all who can help me resolve this issue.

mpg123 also hangs:

And the terminal tab it runs in is completely unresponsive. I can't even Control+C it. I should add at this point that mpg123 is aliased. The alias line in my ~/.bashrc says:
Code:
alias mpg123="mpg123 -o alsa -b 1024 -v"

I don't know why, but I rebooted and now I have sound. Facebook videos are playing correctly, and mpg123 also.

I would mark this as [WORKSFORME] if there was a way to do that. It's not exactly SOLVED...
