Hi fastwings,
the hebrew language support code for KDE and Gnomecan be found in the Slackware package repositories. Look for it
at the Package Browser.
The package for KDE internationalisation for example is this one:
http://www.slackware.org/pb/download...3.2.3-noarch-1
(A little explanation for your understanding: i18n is short for internationalisation, and he is the language code for hebrew (I hope))
Slackware does not seem to be shipping Gnome i18n packages at this time so you will have to look for them some place else. (I could not find any in the three minutes I spent on it. I wish you some better luck.)
also, make sure you configured your system to actually use Hebrew. See what
echo $LANG returns (this environment variable sets the language you want to use on the terminal); set it with
export LANG= (try hebrew or he or something. Neither worked for me but I don't think I have Hebrew language files installed). The desktop environments have their own tools for setting the language they use.
On the sound issue: Do you know which motherboard you have? it is usually possible to find out the sound chip when you know the model. Unfortunately it is possible that the driver for the sound card might be rather hard to configure. You stand a good chance it will work though. If you intend to further investigate the problem (which I highly recommend), you might want to look into using OSS instead of ALSA for sound.
Sorry, I am running out of time. Please post any further information you find out.
