Description of problem:

Once the soundcard detection determines what hardware is available and
installs the appropriate ALSA module, it attempts to play a sound clip
to allow the user to verify that the sound is working properly. The
problem is that when the ALSA drivers are loaded for the first time,
the volume is set to 0 across the board, so even if the correct
drivers are installed, no sound will be produced.

Version-Release number of selected component (if applicable):

firstboot 1.3.3-3
system-config-soundcard 1.2.2-1

How reproducible:
Always when loading ALSA drivers.

Steps to Reproduce:
1. Try to configure a soundcard using the ALSA drivers.
2. Play the test sound.
3. Listen to the sounds of silence.

Actual results:
No test sound is heard.

Expected results:
After loading the alsa drivers it should set the volume to a
reasonable level before playing the test sound. There are a couple of
ways to do this, but probably using alsactl is the simplest.
