Summary:                    ens1371 pcm not work in 2.6.11 kernel
Description: 
I'm using FC3 and my Creative SB AudioPCI 64V sound card works fine in 
2.6.10-1.770_FC3 kernel. After I replaced the kernel to 2.6.11 from
kernel.org or 2.6.11-1.8_FC3 from redhat, there is no sound anymore. I
noticed that the 2.6.11 kernel uses alsa 1.0.8 driver, yet userspace
alsa-lib and utility in fc3 are 1.0.6. So I upgrade them to 1.0.8 too.
Still, there is no sound and alsamixer doesn't show any pcm option.
Fortunately, the 1.0.8 lib and utility backward compatible with 1.0.6
driver in 2.6.10 kernel, so they were kept. The sound card uses ens1371
kernel module. And my /etc/modprobe.conf is this:

alias snd-card-0 snd-ens1371
alias sound-slot-0 snd-ens1371
install snd-ens1371 /sbin/modprobe --ignore-install snd-ens1371 &&
/usr/sbin/alsactlrestore >/dev/null 2>&1 || :
remove snd-ens1371 { /usr/sbin/alsactl store >/dev/null 2>&1 || : ; };
/sbin/modprobe -r --ignore-remove snd-ens1371
alias usb-controller uhci-hcd
alias net-pf-10 off
alias ipv6 off
alias eth0 8139too

Might be some ac97 problem.  Please attach the contents of
/etc/asound.state and /proc/asound/card0/codec97#0/* files.

Hi,

I have attached the files you requested.  Also if I replace the following
files in the current version with those from 2.6.10, then I am able to get
sound working.  Hopefully this will narrow it down a little bit.

sound/core/pcm.c 
sound/core/pcm_lib.c 
sound/core/pcm_memory.c 
sound/core/pcm_native.c 
sound/pci/ac97/*.c 
sound/pci/ac97/*.h 
include/sound/pcm.h 
include/sound/pcm-indirect.h 
include/sound/pcm_params.h 
include/sound/ac97_codec.h 
include/sound/ak4531_codec.h
