Whatever gave you the idea you needed to install Xine or mplayer?  Myth 
uses its own internal player to play back recorded programs.  You only 
need an external player if you want to play back non-Myth content using 
the MythVideo plugin.

The reason you can't watch LiveTV is likely because your sound card or 
driver doesn't support (or isn't configured properly for) full duplex.

The reason you have no sound when you play back a recording is likely 
because your recordings have no sound (i.e., your sound is 
mis-configured for Myth).

Read the section in the docs about troubleshooting audio (http://
www.mythtv.org/docs/mythtv-HOWTO-7.html and http://www.mythtv.org/docs/
mythtv-HOWTO-20.html#ss20.11 & try to get your audio configured 
properly.

PS- In future, it would be helpful to submit your system specs when 
asking for help.  Include things like: motherboard, CPU, sound card, 
video card, Linux distro, sound drivers, video card, tuner card, 
version of Myth & source of Myth (i.e., RPM, Deb, source tarball or 
CVS)
