@loboris:
1. On github you created project from file posted on orangepi.org ?
2. Do you know maybe, is it connected with https://github.com/orangepi-xunlong/linux-sunxi or something any know source branch ?
I need to apply some patches but Is it possible to find where the branch come from and where started ?

Your Ubuntu distro for Orange Pi PC works great except the analog audio from the AV/CBVS jack is not working. No audio from this jack with Headphones plugged-in. On Android it is working. Any fix? I can only use the HDMI audio, it works great. Anyway we thank you for what you have done for the OrangePi community.

Thanks, it works now.

@Loboris: Thanks for your response. This did the trick

Still got one question: there is a cpu freq applet in the debian taskbar, when i change the settings and go back to the desktop the settings are set back to default...
How can i make changes to the settings so that the cpu freq will change?
I need real time scheduling for audio purposes so i need max freq at all time. (I use a cpu cooler and fan)

you can try this to lock the cpu to max freq:

echo performance > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor

Loboris,
I think that's referring to lymon's response (post #616) to my post (#615) back on page 62 in response to some weird linking within the /lib/modules/3.4.39/ directory:

You will need kernel headers (this is the 'build' error you are getting) or build the kernel from source and include the drivers (if not already included in the kernel source tree) loboris kernel source tree can be found here: https://github.com/loboris/OrangePI-Kernel (but it seems to have 'kernel-panic' problems once compiled)

@loboris,
/lib/modules/3.4.39/build points to /home/LoBo2_Razno/OrangePI/kernel_3.4.9/linux-3.4

I am trying to compile a wifi driver that does
make -C /lib/modules/3.4.39/build SUBDIRS=/home/orangepi/DPO_RT5572_LinuxSTA_2.6.1.3_20121022/os/linux modules

so it obviously doesn't work on my machine. Where should the link point and what should be in the directory it points to?

@loboris,
/lib/modules/3.4.39/build points to /home/LoBo2_Razno/OrangePI/kernel_3.4.9/linux-3.4

/lib/modules/3.4.39/build symbolic link is created during the kernel build and it points to the linux kernel source root directory.
You can clone my github repo, there will be the linux-3.4 directory. You can create new /lib/modules/3.4.39/build pointing to that directory.

You can use build_mali_driver.sh script as an example how to build only specific modules.
