>Description:
I've Packard Bell A8810 laptop

- The audio codec seems to be a Conexant 20468-31 AC'97:

- This laptop seems quite similar to Benq JoyBook S53 and NEC Versa s940:

Loading 'snd_ich' kernel module dmesg states:

pcm0: <Intel ICH6 (82801FB)> port 0x1c00-0x1cff,0x18c0-0x18ff mem 0xb0040800-0xb00409ff,0xb0040400-0xb00404ff irq 17 at device 30.2 on pci0
pcm0: <Unknown AC97 Codec (id = 0x43585431)>

and there is no audio output.


Trying to add:

{ 0x43585431, 0x00, 0, "CX20468-31",    0 },

to

/usr/src/sys/dev/sound/pcm/ac97.c


albino# kldload snd_ich gives

pcm0: <Intel ICH6 (82801FB)> port 0x1c00-0x1cff,0x18c0-0x18ff mem 0xb0040800-0xb00409ff,0xb0040400-0xb00404ff irq 17 at device 30.2 on pci0
pcm0: <Conexant CX20468-31 AC97 Codec>

but still no sound!

Thanks in advance,

Dave



PS: Same problem on Linux with ALSA
