To check if the sound is working, try to play an mp3 with xmms
. First, type xmms to see if it's installed. If not, install xmms now (it's in your Redhat CD's
). Redhat cannot play mp3's right out the box.
If you cannot hear anything, you need first to get and install a plugin from here:
When it's done, make sure you have a Video Player installed. Xine is a very good DVD, DivX, MPG, VCD player and it's in your Redhat CD's. Type xine at the terminal to see if it's installed. If not, xine is in your Redhat CD's
The best one so far though, is mplayer. If you are unhappy with xine performance check this forum after mplayer
There're really easy ways to install it with Redhat.
