hedmo,
emerge --sync
emerge -1 gentoo-sources
copy your old .config file from the current kernel to the new kernel
cd the new kernel
run make oldconfig
rebuild and reinstall your kernel.
update grub.conf
fix the /usr/src/linux symlink
rebuild any third party code theta builds against the kernel.
reboot into the new kernel

at the moment i am making a emerge --newuse --update --deep --ask --verbose world
but
mybox ~ # emerge -av gentoo-sources grub
* IMPORTANT: 3 news items need reading for repository 'gentoo'.
* Use eselect news to read news items.
These are the packages that would be merged, in order:
Calculating dependencies... done!

mybox ~ #
so i am up to date
is that the way to update to a new kernel 
i have always made a manually (make menuconfig) update to update my kernel |

hedmo,
That has pulled the kernel sources onto your system but no more. Kernel gentoo-sources-2.6.35-r10 is available for you to configure, compile and install, just as you did when you installed gentoo.
You either used genkernel or you configured your own kernel. You still need to | Code: | copy your old .config file from the current kernel to the new kernel
cd the new kernel
run make oldconfig
rebuild and reinstall your kernel.
update grub.conf
fix the /usr/src/linux symlink
rebuild any third party code theta builds against the kernel.
reboot into the new kernel |
if you do it the manual way or do to choose your newest kernel, then run genkernel if you are a genkernel user.

i have configured my the new kernel by doing this:
hedmo@mybox ~ $ su
Password:
mybox hedmo # mount /dev/md1 /boot
mybox hedmo # cd /usr/src/linux
mybox linux # make menuconfig
fixing my kernel and:
mybox linux #make && make modules_install
mybox linux #cp arch/x86_64/boot/bzImage /boot/kernel-2.6.35-gentoo-r10
mybox linux # ls /boot
boot kernel-2.6.34-gentoo-r2 kernel-2.6.35-gentoo-r5
grub kernel-2.6.35-gentoo-r10 lost+found
kernel-2.6.31-gentoo-r10 kernel-2.6.35-gentoo-r2
mybox linux # reboot
i dont need to eselect the new kenel.it will be in /usr/src/linux direct.if i want to configure another kernel i use eselect.
and if i want to test another kernel i switch at boot by edit grub

That shows that the /usr/src/linux symlink on your kernel is not updated when you get a new kernel.
What does show now?
I suspect you have remade your old kernel.

my old kernel was 2.6.31-gentoo-r10
i have put the symlink away from /etc/make.conf .there was one day i missed a kernel update and i cleaned the old one.so i dont want to make that
mistake one more time thats why (-symlink) in make.conf
is it possible you can help me with my sound to.please |

hedmo,
2.6.35-gentoo is the kernel you are running but you expected 2.6.35-gentoo-r10
Its odd that it says 2.6.35-gentoo #1, which means its the first build of that kernel.
The Sat Aug 7 11:30:13 GMT 2010 is the kernel build time, so you are clearly not running the kernel you think you are.
I can help you with your sound but lets get you running 2.6.35-gentoo-r10 first because fixing your sound will probably mean fixing your kernel, so its key that we work with the right kernel. Lets fix that first.

hedmo,
Good, as you say, thats much better.
To start on your sound, we need to know what sound devices you have.
PCI connected sound devices will be shown by lspci
USB connected sound devices will be shown by lsusb. Webcams with microphones count as sound devices.
Please post the output of both lspci and lsusb with all your sound devices connected.

hedmo,
alsa-driver is a bad choice. It often gets out of step with the kernel, which causes problems. If it built and installed OK we can leave it for now.
On the good news front | Quote: | | card 0: SB [HDA ATI SB], device 0: ALC892 Analog [ALC892 Analog] |
card 0 is your analogue card. Card 0 is also the default sound card.
Run alsamixer. Turn off all switches (mute) except Master, PCM and Front Stereo. You may not have them all as different cards name them differently.
Set the sliders above those switches, which should be on, to about 70%
Check that your front speakers are connected to the pale green socket on your sound card.
Play some music from your hard drive
Getting the Mute right is key as HDA sound cards can operate at two sample rates 44.1kHz and 48kHz, but only one rate at a time. 44.1 is used for analoge and 48 for digital sound. If any digital channels are enabled, all of the analogue ones are off.
When you make it work from the front speakers, you can try the controls one at a time to be able to add more sources and more outputs. Oh. If this system has a headphones channel, that must be off to start with too.

I have tryed build in kernel,kernel modules and now of kernel
alsa-driver.all the same.I have muted all my digital outputs and set all my
analog outputs to full volume and unmute even PCM and master
but I think you got the answer. I can not mute my headphones and maybe
that's the problem because I can hear the sound if I set my amp to max but it's
badly low. |

hedmo,
You are hearing crosstalk between one sound channel and another or the must is not perfect.
Read less /usr/src/linux/Documentation/sound/alsa/ALSA-Configuration.txt, also less /usr/src/linux/Documentation/sound/alsa/HD-Audio-Models.txt
and less /usr/src/linux/Documentation/sound/alsa/HD-Audio.txt
The Intel-HDA driver does not always detect your hardware properly, so when the module loads, you may need to help it with a module parameter.
The routine is
| Code: | | modprobe -r snd_hda_intel |
to remove the module. If its in use, you must remove the module thats using it first.
| Code: | | modprobe -r snd_hda_intel <parm>=<value> |
For <parm> you will want model, so its | Code: | | modprobe -r snd_hda_intel model=<value> |
Various <values> are listed in the files above.
Rinse and repeat. When you find one that works, we can automate it

i have read the txt and there is most for laptops as i understod.i dont fully understand it.
can you give me more info to start with.like
Code:
modprobe -r snd_hda_intel <parm>=<value>
i understand what you want me to do but not <parm>=<value>.i am not so good at english and this sort of things.
i missed the hda-audio-models.txt too read but as i can see my card is not there only ALC882/883/885/888/889 |

hedmo,
Your sound interface is in two parts. snd_hda_intel is the kernel driver for the hardware exposed to the kernel.
Chips like ALC882, and many others, provide the codecs. The kernel tries to detect which codec chip you have but sometimes it gets it wrong.
Trying them all is harmless.
First, you must remove the module
| Code: | | modprobe -r snd_hda_intel |
removes the module, so you can reload it. You need to do this to set module parameters.
Now you can try | Code: | | modprobe snd_hda_intel model=alc880 |
and test. If it works, make a note of model=alc880 so we can automate it.
If not, move onto the next one
| Code: | modprobe -r snd_hda_intel
modprobe snd_hda_intel model=acl260 |
and so on.
What do you have in /dev/snd ?

hedmo,
Your /dev/snd shows you have two sound cards controlC0 and controlC1
Card0 has some bits missing
| Code: | controlC0
hwC0D0
pcmC0D0c
pcmC0D0p |
is all good, thats the control interface and front stereo playback and capture devices.
Then Card0 goes to pcmC0D3p ... thats device 3 playback.
Now if it has a device 3, it should also have a device 1 and 2.

I got some problem with the modules. I have --unmerge
alsa-driver and alsa-headers and put alsa away from
my kernel but still the modules shows in lsmod.I have
disable force modules to load in kernel and put alsasound
away from rc-update boot. if i remove modules manualy
and load others,i get the old ones back in use
when i start alsa.if is want to get the old modules
away,i have to disable sound support from my kernel. |

hedmo,
Look in /lib/modules/`uname -r`/.... for alsa modules, or try
The kernel modules and alsa-driver modules install in two different places.
It is possible to get both sets installed, which is a really bad idea. Harmless to the hardware but it won't work.
If you are not completely sure that you only have the kernel modules, rebuild and reinstall your kernel starting with the step.

hedmo,
kernel drivers are preferred over emerge alsa-drivers.
Remove alsa-drivers and add the kernel modules as modules.
Before you touch the kernel, be sure that shows that alsa-driver/ has gone, or at least, is empty.

okej away with alsa-driver,alsa-headers,alsa-utils and clean /lib/modules/2.6.36-rc8-git5/alsa-driver
but alsa-driver is still there |

hedmo,
The kernel sources and alsa-drivers are two different places to get what in an ideal world would be the same thing.
You need everything else in the ALSA guideexcept emerge alsa-drivers.
The kernel modules and alsa-drivers even provide the same *.ko files.
Your /lib/modules/2.6.36-rc8-git5/alsa-driver directory can remain, as long as its empty.
