Welcome to Sabayon Linux, which is far superior to Ubuntu 6.06 (as a previous long-time user of Ubuntu 6.06 myself, I'm allowed to say that!)

Open a Terminal window, login as the root user and try running the alsaconf command to set up your audio card. Then run the alsamixer command and adjust the sliders to make sure none are at zero, and unmute anything that shouldn't be muted. (N.B. use the TAB key to page between the different AlsaMixer pages in the Terminal window.

Thanks a lot for the mail. I tried alsaconf - it correctly detected my sound card. But no sound yet.
I also fiddled with alsamixer. What is wrong?

Hello all,
Unfortunately modprobe snd-hda-intel also did not make it work. What more output do you require from me.
Even wifi is not working out of box.
As a matter of fact, I just tried Mandriva 2009 and everything including sound and wifi worked out of box.

Regards,
Shantanu

Update - wifi started working after (unnessary) 1/2 hour playing with knetworkmanager.
Sound no luck yet. I need your advice on this still.
Regards,

rmmod snd_hda_intel
modprobe snd_hda_intel 82801G

Well, looking at your original lspci -v output, you have the same Intel audio controller as in my laptop (see excerpt below), in which the audio works perfectly, so all is not yet lost:

Code: Select all
00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)
        Subsystem: Acer Incorporated [ALI] Device 0092
        Flags: bus master, fast devsel, latency 0, IRQ 22
        Memory at b0000000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: [50] Power Management version 2
        Capabilities: [60] MSI: Mask- 64bit+ Count=1/1 Enable-
        Capabilities: [70] Express Root Complex Integrated Endpoint, MSI 00
        Capabilities: [100] Virtual Channel <?>
        Capabilities: [130] Root Complex Link <?>
        Kernel driver in use: HDA Intel
        Kernel modules: snd-hda-intel


Looking at your lspci -v output (see excerpt below), you did not appear to have the kernel driver HDA Intel in use nor the kernel module snd-hda-intel loaded:

Code: Select all
0000:00:1b.0 0403: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)
        Subsystem: Hewlett-Packard Company: Unknown device 30b2
        Flags: bus master, fast devsel, latency 0, IRQ 66
        Memory at d4340000 (64-bit, non-prefetchable) [size=16K]
        Capabilities: [50] Power Management version 2
        Capabilities: [60] Message Signalled Interrupts: 64bit+ Queue=0/0 Enable-
        Capabilities: [70] #10 [0091]


What does you lspci -v output for the 82801G controller look like now, after doing the various things that wolfden and I suggested in earlier posts? Still the same, or does it now show the driver in use and the kernel module?

Also, what laptop model are you using? Judging by your lspci output, I would guess it's an HP model. If you search for the specific model number and "audio" or "sound" using the SL Forums Search facility and also the search facility on the Gentoo Forums, perhaps you will find a thread about your specific laptop.
