[mythtv-users] No sound after compile mplayer-1.0pre5-ivtv from Chris site

[mythtv at pdebrabander.nl]

I've compiled the mplayer, which is packed with the ivtv from Chris.
When i execute ./configure the Alsa is set to NO.
Compiling went ok, and mplayer is working fine, but there is no sound.

When i try ./configure --enable-alsa, it gives : error in line ....

For the information, i'm using FC2 with rpm's from Axel's site.

What can here be the problem ?
