Hi Andreas,
can you try this patch? it should show up in the log very often. it prints a bitmask of native formats that asterisk support. if it is 0, we should find out why.
I patched it manually and i cannot see nothing from the logs: http://pastebin.com/6wt7tAb0
This is the code patched [1] , obviously i run make uninstall and make clean before re-compiling.
The lcr's version has been taken fromĀ git://git.misdn.org/lcr.git/ some days ago and Asterisk is 1.6.2.5.

Thank you for attention.
