OK, it did the trick. Thanks. I have some trouble with Tfilenameedit. If using: uos_LoadLib(Pchar('/home/fred/uos_mse/lib/Linux/64bit/LibPortaudio-64.so')) -> it works. But when using: Afilenameedit.value := '/home/fred/uos_mse/lib/Linux/64bit/LibPortaudio-64.so' ; uos_LoadLib(Pchar(Afilenameedit.value)) ; -> it does not work. Do you have a idea why it does not work ? Thanks. Fre;D
