I am having some difficulties with fxotune on asterisk 1.20beta1. I followed the information on the wiki about running fxotune and made sure to stop asterisk, etc. When running fxotune -i 4 I get the following error message Could not fill the input buffer Tuning module 1.failure Could not fill the input buffer Tuning module 3.failure Could not fill the input buffer Tuning module 4.failure The interesting this is that module 2 will run properly. If I look at the fxotune.conf there is information in it for module 2. I couldn't find any other information on this error. Can anyone help? Thanks Ben
