I get this sound error while running ET(please help)

I am using Intrepid

This is the error I get when trying to play ET

------- sound initialization -------
/dev/dsp: Device or resource busy
Could not open /dev/dsp
------------------------------------
Sound memory manager started
Sys_LoadDll(/home/nakama/.etwolf/etmain/ui.mp.i386.so)... 
Sys_LoadDll(/home/nakama/.etwolf/etmain/ui.mp.i386.so) failed:
"/home/nakama/.etwolf/etmain/ui.mp.i386.so: cannot open shared object file: No such file or directory"
Sys_LoadDll(/usr/local/games/enemy-territory/etmain/ui.mp.i386.so)... ok
Sys_LoadDll(ui) found **vmMain** at  0xa9247f40  
Sys_LoadDll(ui) succeeded!

I have tried installing "esound" and nothing happens.

I have also tried this command "killall esd; et; esd"

and this "echo "et.x86 0 0 direct" > /proc/asound/card0/pcm0p/oss" note: with this command I get permissions denied error so I tried to run as sudo and get the same permissions denied error so the only way I found to execute it was first doing "sudo su"

But I still am having no luck

any help would be great.

I have already looked at https://help.ubuntu.com/community/EnemyTerritory still did not help.

Do u have any other sound programs running when u get this? Like teamspeak, ventrilo or music players. Anyway This worked for me.

do:

sudo sh -c "echo 'et.x86 0 0 direct' > /proc/asound/card0/pcm0p/oss"
sudo sh -c "echo 'et.x86 0 0 disable' > /proc/asound/card0/pcm0c/oss"

start et and see if it helped. If it did help here is how u make it permanent.

1. Open file /etc/rc.local:

sudo gedit /etc/rc.local

1. Add following lines to the file:

echo 'et.x86 0 0 direct' > /proc/asound/card0/pcm0p/oss
echo 'et.x86 0 0 disable' > /proc/asound/card0/pcm0c/oss

*before* the last line:

exit 0

1. Save the file and close it.
