Hi everybody,

I have a HP DV6 (model 2147el) and have installed gentoo 10.0 kernel 2.6.31-r10 on it. My hardware specification (lspci) is following

You'll want to use ALSA, and you'll want to use modules. Post your lspci -n and I'll take a closer look at it.

okay this is the output of lspci -n

Hm. You've got one of those troublesome snd-intel-hda + nvidia combos.

OK. First try compiling your kernel with snd-intel-hda as a module, add it to /etc/conf.d/modules, and reboot (so that the new kernel loads). Then try opening alsamixer and raising the gain to maximum.

i recompiled my kernel so the said driver snd-intel-hda is a module and added it to /etc/modules.autoload.d/kernel-2.6. I increased all audio levels in alsamixer. The result is same. No Audio ..... But when I plugin head phones, there is a very very very very low sound coming out.

Which kernel version are you using?

Can you post emerge --info and a link to your kernel config (It's a long file so if you can upload it somewhere - pastebin? and link to it, it'll make it easier to read this thread)?

Here are the two details:

emerge --info http://pastebin.com/0kJA0Nd3
.config http://pastebin.com/FXWHLi1G

I am using kernel gentoo-sources 2.6.31-gentoo-r10.
Right now I am trying it on gentoo-sources 2.6.33 and will let you know about it's outcome when i am done.

A couple of things, if you're just going to start a new config:

1. Use Pappy's Kernel Seeds: http://kernel-seeds.org

2. Give zen-sources a try. It might turn on a few bells and whistles. Pappy has configs for zen-sources as well as gentoo-sources.

I'll look at your .config in a bit and see if I can spot any missing sound drivers.

Some experiments:

1. Same result (no sound) for Pappy Kernel seeds. I tried it for kernel 2.6.31 (the one which I currently have).

2. With gentoo-sources 2.6.33 and with zen-sources 2.6.33, alsamixer does manage to show both Intel and Nvidia devices. When I play something using aplay, I only get garbled noise as if some radio has been left on some un-tuned frequency. So I do get something from the speakers, unfortunately it is just noise.

See what happens if you completely disable OSS. You really don't want that anyway.

Okay so I tried madplay instead of aplay on gentoo-sources 2.6.33 and the sound is perfect.

Another problem which is also solved now, on the new kernel (2.6.33) while trying to recompile nvidia drivers, I would get the message that the kernel sources cannot be found and that I should check if they are installed. How that is solved is by adding the following entries into package.keywords

sys-kernel/gentoo-sources ~amd64
x11-drivers/nvidia-drivers ~amd64
x11-libs/libvdpau ~amd64

That recompiles the drivers.

audiodef thanks for your help. you really deserve a treat :-)

my new laptop is finally working after 2 weeks.

It looks like you solved it yourself, but whatever I did to help, I'm glad.
