Recordings out of sync - using mixmonitor

I use trixbox CE 2.6.0.2-vmware. All calls with are recorded are out of sync. i.e there is about 5 secs delay between our phones and the other persons, though the actually call is fine, it is just noticed when listening to the file.

I found some solution for that here:

svn.digium.com/view/asterisk?vie … ion=109173

bugs.digium.com/view.php?id=12187

but can anybody tell me how to compile and use fixed files/components?

regards,
Marek
