Description Jordi 2005-12-11 04:49:24 UTC

Most recent kernel where this bug did not occur: 2.6.12.1

Distribution: Debian Sarge

Problem Description:
I have recently upgraded from kernel 2.6.12.1 to 2.6.14.3 in Debian Sarge (make
oldconfig). I had a SB Live card working with Alsa (Chip: SigmaTel STAC9758,59)
After upgrading sound stop working.

I have solved the problem following the instructions in
http://alsa.opensrc.org/emu10k1 :
/***********/
In alsa-driver/alsa-kernel/pci/ac97/ac97_codec.c is the line

{ 0x83847658, 0xffffffff, "STAC9758/59", patch_sigmatel_stac9758,        NULL }, 

change it to

{ 0x83847658, 0xffffffff, "STAC9758/59",        NULL,   NULL },

The patch is wrong.  It will break many other boards.

Please try the latest kernel at first.  It should have been fixed.

Comment 3 Adrian Bunk 2006-04-15 06:17:35 UTC

I'm assuming this issue is already fixed.

Please reopen this bug if it's still resent in kernel 2.6.16.5.
