location of Mythtv directory in Linux MCE??

[ferdies]

What's the location of Mythtv directory.  I am trying to locate settings.pro

According to this site: http://www.mmalson.com/mythtv/
-----------------
Configuring the sound card
For some reason, MythTV does not default to using the ALSA sound system. So, I had to edit the settings.pro file in the mythtv directory to uncomment the following lines:
   CONFIG += using_alsa
   ALSA_LIBS = -lasound
---------------
This may solve my problem of not having sound in MythTV Live TV.

or this is really true
