Description of problem:
After upgrading from kernel-2.6.12-1.1456_FC4 (official version for FC4)
to kernel-2.6.13-1.1526_FC4 (official successor), some mixer controls
like "Master" and "PCM" are missing from all mixer tools like
alsamixer or gnome-volume-control.

Furthermore, the sound output remains silent. My sound card is a
Creative Soundblaster Live. alsamixer identifies it as
"SBLive! Platinum 5.1 [SB0060]". My PC is a Dell Dimension XPS T600
(Pentium III at 600 MHz - yes, it's slow, but good enough for sound ;-)

I've never had such strange behaviour before. https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=168668
describes the same bug, but for FC5.
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=169152
mentions some backported emu10k1 fixes from kernel 2.6.14
which might be related somehow to the new problem.

To make sure that the problem is not related to weird mixer settings,
I deleted /etc/asound.state and did a "mkdir /etc/asound.state" which
effectively keeps the system from storing any mixer settings and
forces fresh default mixer settings after reboot. However, mixer
settings don't make any difference.

Version-Release number of selected component (if applicable):
kernel-2.6.13-1.1526_FC4

How reproducible:
Always

Steps to Reproduce:
1. Boot with kernel-2.6.13-1.1526_FC4
2. Run alsamixer (or any other mixer tool)
3. There's no "master" volume control (usually left of headphone settings)
4. Alternatively, run "system-config-soundcard" which complains about missing mixer controls

Actual Results:  The mixer controls "Master" and "PCM" (and maybe others, haven't
compared them one by one) are missing and no sound can be heard.

If I run "system-config-soundcard" (as root) to re-detect my sound
card, it detects the SB Live but when playing the test sound it
outputs these error messages:

amixer: Unable to find simple control 'Master',0
amixer: Unable to find simple control 'PCM',0
amixer: Unable to find simple control 'PCM-2',0
amixer: Unable to find simple control 'DRC Range',0


Expected Results:  Well, I expect to have all mixer controls and to hear sound. ;-)
