BB xM audio output port problem

Hi
I am using 2.6.38 kernel with ubuntu-desktop . On audio output port,
no signal. I can not get any sound for a .wav file and also from the
sound preferences menu, when test the hardware no sound output again.
Is there any settings to fix it ?

It should be fixed with:

http://bazaar.launchpad.net/~beagleboard-kernel/+junk/2.6-stable/revision/189

Can you verify, build and test it for us

bzr branch lp:~beagleboard-kernel/+junk/2.6-stable

cd 2.6-stable

./build_kernel.sh

hi
When I build the patch, that the script build_kernel.sh is processing, the electricty was cut off and the BB restarted, so the changes was not implemented. Can I continue from the corrupted point to build or will I start scratch from ?

Build it on an x86 instead, it should take more then 15mins, vs the
5-6 hours on the beagleboard..

Can I continue from the corrupted point to build or will I
start scratch from ?

Not easily, the script is designed to make sure you get a good build,
no matter what.. So it always starts from a fresh start..

I have compiled the package on x86 with cross-compiler. An in the 2.6-stable directory, there are theese files and directories. What will I do after this point ?

build_deb.sh
build_kernel.sh
create_dsp_package.sh
create_sgx_package_2.6.37.sh
create_sgx_package.sh
deploy
dl
KERNEL
patches
patch.sh
readme.txt
system.sh
system.sh.sample
tools
version.sh

Copy the uImage and modules from the "deploy" directory.

Copy to where ?
deploy directory consists
2.6.38.2-x1.2-headers.tar.gz 2.6.38.2-x1.2-modules.tar.gz 2.6.38.2-x1.2.uImage headers mod

modules in the directory of mod/lib is it right ?

I could not understand how can I fix the audio problem after this point ?

Copy to where ?

To the mmc card you boot your beagle with, where else where you thinking?

deploy directory consists
2.6.38.2-x1.2-headers.tar.gz 2.6.38.2-x1.2-modules.tar.gz
2.6.38.2-x1.2.uImage headers mod

2.6.38.2-x1.2.uImage goes to the "boot" partitions as "uImage"

sudo cp -v ./deploy/2.6.38.2-x1.2.uImage <mounted ocation of mmc fatfs

/uImage

2.6.38.2-x1.2-modules.tar.gz is the matching modules.. Need to be
untarred to the "rootfs"

sudo tar xfv ./deploy/2.6.38.2-x1.2-modules.tar.gz -C <mounted ocation
of mmc rootfs partition>/

That is, I will format the mmc card and will copy the image files scracth from. But I want to fix the problem on my working system, is it impossible ?

There is no reason to 're-format' the mmc.. just copy the uImage and
modules to your current working mmc card...

I have copied the files to uSD card but not fixed audio output
