I know linphone uses speex in echo cancel,  but I don't know  if it has different effect between using OSS driver and ALSA driver? welcome the replies!

As I understand, in theory echo cancellation is done by speex, so underlying hardware/drivers/library should not affect it. However, in practice, many element in system may affect it.
