joybook S52 Soundcard AC97 not working (unknown codec)


Normally i will use Gentoo, but for testing purposes i installed SUSE 10.0 on my Benq Joybook S52

My Soundcard isnt working (amarok looks like playing, but no sound output), updated the Kernel to 2.6.15 and alsa to 1.0.10.

lspci | fgrep audio
00:1e.2 Multimedia audio controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller (rev 04)

the device is shown up under Windows XP "conexant ac-link 2 channel audio

seems to be initialized ok for me...


cat /proc/asound/cards
0 [ICH6 ]: ICH4 - Intel ICH6
Intel ICH6 with unknown codec at 0xb0040800, irq 11

maybe the "unknown codec" part is the bad part....

volume is of curse unmuted and turned up.

i would be happy for any hint

EDIT: when i unmute IEC958 with alsamixer a red light goes on and off in the headphone jack (light is on under windows)

when i turn mixer up und unmute a lot of things i hear every time i change a value in alsamixer a cracking sound

Hi Mahatmah,

I've been wandering the Web for a solution too, as I also own a BenQ Joybook S52. Almost everything works with my Linux distro, MEPIS, except sound and ACPI. I wonder if you've found a solution? Would appreciate it if you could also share it with me

Hi,

there is currently no chance to get sound working...i am looking for an external audio device.

ACPI...working fine for me..with latest Ubuntu-Beta even the battery works out of the box..without debugging DSDT Table
