We try the update, did not help, we try update lastest drivers, not help....... if we disconnect the echo cancelation module the card works ok, only a few calls with echo, if we connect the echo cancelation module , we have echo in all calls, we supose the module is defective in some way, the dmesg log says that is activated and if i try other echo cancelation hardware like de115 or the de210 works great. I need to know if it is defective hardware
