Before I start the mixer, the following modules are loaded:
snd-mixer-oss          16184   0 (autoclean) (unused)
snd                    47812   0 (autoclean) [snd-mixer-oss]
soundcore               7076   0 (autoclean) [snd]

If I start mixer at this point, I can't adjust any of the settings.  On the
other hand, if I manually load "alsamixer" and then exit, the following modules
are loaded:

snd-intel8x0           24936   0 (autoclean)
snd-ac97-codec         59676   0 (autoclean) [snd-intel8x0]
snd-pcm                88160   0 (autoclean) [snd-intel8x0]
snd-page-alloc          9108   0 (autoclean) [snd-intel8x0 snd-pcm]
snd-timer              20676   0 (autoclean) [snd-pcm]
gameport                3524   0 (autoclean) [snd-intel8x0]
snd-mpu401-uart         5664   0 (autoclean) [snd-intel8x0]
snd-rawmidi            18944   0 (autoclean) [snd-mpu401-uart]
snd-seq-device          6028   0 (autoclean) [snd-rawmidi]
snd-mixer-oss          16184   0 (autoclean) (unused)
snd                    47812   0 (autoclean) [snd-intel8x0 snd-ac97-codec snd-pc
m snd-timer snd-mpu401-uart snd-rawmidi snd-seq-device snd-mixer-oss]
soundcore               7076   1 (autoclean) [snd]

Should loading the mixer cause the modules for the sound card to be loaded
automatically? or is that my responsibility before loading the mixer?


Reproducible: Always
Steps to Reproduce:
1. reboot system
2. start xfce
3. try using mixer - there are no options to adjust
4. run alsamixer, and exit
5. re-run mixer - now you can adjust settings




Expected Results:  
I would have expected that when the mixer was loaded, everything would have
automagically loaded (like when I called alsamixer manually), and happiness
would overcome me.
