Comment 6 for bug 858175

I found a solution:

sudo mkdir /lib/modules/3.0.0-12-generic/source
sudo ln -s /usr/include /lib/modules/3.0.0-12-generic/source/

then I had some permissions issues:

anjinhuviny@viny-server:~$ ossmix
/dev/mixer: Permission denied
anjinhuviny@viny-server:~$ osstest
Sound subsystem and version: OSS 4.2 (b 2005/201110151348) (0x00040100)
Platform: Linux/x86_64 3.0.0-12-generic #20-Ubuntu SMP Fri Oct 7 14:56:25 UTC 2011

*** Scanning sound adapter #-1 ***
/dev/oss/oss_cs42810/pcm0 (audio engine 0): CS4281
- Performing audio playback test... /dev/oss/oss_cs42810/pcm0: Permission denied
Can't open the device

*** Some errors were detected during the tests ***

the solution to these problems are simple:

sudo chmod 777 /dev/mixer
sudo chmod 777 -R /dev/oss
