Sound Issues
There are a few methods you can try if you are having problems with sound:
Method 1
You can try stopping the ESD sound server before running the game by running:
killall esd; et; esd
If this works for you then you can create a script to run it. To do this create a new text file called start-et and add these lines to it:
#!/bin/sh
killall esd
et
esd
exit 0
Now save the file and you will need to run these commands to make it executable and to put it somewhere in your user's $PATH variable (so that it can be executed by just typing it's name):
chmod a+x start-et
sudo cp start-et /usr/local/games
If you don't want to put it in /usr/local/games you don't have to, but remember to specify whatever path you decide to give it whenever you execute it (some paths can use shortcuts, like ./start-et for the current directory, ~/start-et for your Home directory, etc.)
Method 2
If you don't hear any sound and see the following error message in a terminal:
/dev/dsp: Input/output error
Could not mmap /dev/dsp
You will need to do the following in addition to the steps above:
sudo -i
echo "et.x86 0 0 direct" > /proc/asound/card0/pcm0p/oss
echo "et.x86 0 0 disable" > /proc/asound/card0/pcm0c/oss
exit
This makes the script slightly more complicated, since parts of it will need to be run with superuser priviledges. To use the above commands in the star-et script described in Method 1 you should make it look like this:
#!/bin/bash
gksudo echo "et.x86 0 0 direct" > /proc/asound/card0/pcm0p/oss
gksudo echo "et.x86 0 0 disable" > /proc/asound/card0/pcm0c/oss
killall esd
et
esd
exit 0
Then use the commands to give it execute permissions and to put it in /usr/local/games.
Making Startup Scripts More Friendly
If either of the above scripts fix your problem then you can add them to the system's menu using the Alacarte Menu Editor in Applications->Accessories. Go to a suitable location such as Games and make a new entry. It's Command should be start-et (as long as it is in /usr/local/games. If you put it somewhere else then put the whole path), set the icon, name, etc. to what you want then press OK. To avoid confusion you should also disable the old Enemy Territory entry which was added by the installer by unticking the box next to it in Alacarte.
