Several mixer fields go missing from snd-emu10k1 with 1558 kernel

Description of problem:
After booting into kernel 1.1558_FC5, several mixer components are missing in
alsamixer, gnome-volume-control etc.
Version-Release number of selected component (if applicable):
Boot into it.
Steps to Reproduce:
1. Boot into 1558_FC5 kernel
2a. Run alsamixer, or
2b. Start X and open gnome-volume-control
Master and PCM volume controls are missing. Only headphone, headphone LFE etc
appear. Card remains muted, basically.
Master and PCM should appear.
I booted back into 1.1555_FC5 just to make sure it wasn't something else. It
still works fine there.
(also a problem in 1.1560_FC5
What kernel versions are 1555, 1558 and 1560 in FC5?
I've got the same problem with FC4 when upgrading from
kernel 2.6.12-1.1456_FC4 to 2.6.13-1.1526_FC4
Just for curiosity ...
There was a patch to add "sb live platinum" support and it seems to have made a
bit of a hash of things.
It appears to likely be this change:
which pretends there is no AC97 codec on the board and thereby disables the
actual outputs from the card.
Whoever tested it obviously has a completely different board to mine :)
yes. I found this this afternoon, as it hit the FC4 update I pushed out. It'll
be fixed in the next rawhide kernel I build.
Any ETA before next FC4 update ?
fyi, I did try taking this upstream to alsa project, but their bugtrack wouldn't
even let me connect earlier, and is now making it difficult to sign up to login
(how can they have mail problems delivering to gmail.com?)
