Description of problem: sound broken. Player shows that it plays music but no sound from speakes. I see error messages in dmesg like this: Dec 10 15:13:32 localhost kernel: ALSA sound/core/pcm_native.c:1940: BUG?

I can confirm on my hardware as well. [kathryn@Galaxy ~]$ cat /proc/asound/cards 0 [Intel ]: HDA-Intel - HDA Intel HDA Intel at 0xd4240000 irq 22 [kathryn@Galaxy ~]$ rpm -q kernel kernel-2.6.27.5-41.fc9.i686 kernel-2.6.27.7-53.fc9.i686 kernel-2.6.27.9-73.fc9.i686
Same is in Fedora 10 with: HDA-Intel - HDA Intel HDA Intel at 0xfc400000 irq 22 kernel-2.6.27.7-134.fc10.x86_64 Kernel 134 works flawless kernel-2.6.27.9-159.fc10.x86_64 Kernel 159 no sound.
Created attachment 328458 [details] Patch to revert ALSA 1.0.18a import. The regression seems to have been caused by this change: * Mon Dec 08 2008 Chuck Ebbert <cebbert> 2.6.27.7-139 - ALSA 1.0.18a Dropped patches: linux-2.6-alsa-ac97-whitelist.patch linux-2.6-alsa-ac97-whitelist-AD1981B.patch linux-2.6-alsa-revo51-headphone.patch linux-2.6-olpc-speaker-out.patch This patch against 2.6.27.10-168 on the F-10 branch restores sound support on my machine.
Could this patch be reverted? There is a lot of duplicates to this bug, a lot of them seems to stem from that patch being dropped.
With the kernel update I installed from yum today, I now have sound. [kathryn@Galaxy ~]$ uname -a Linux Galaxy 2.6.27.12-78.2.8.fc9.i686 #1 SMP Mon Jan 19 20:14:35 EST 2009 i686 i686 i386 GNU/Linux
