When I check the audio sample contained in switch_frame::data array, it always has the same value -1, regardless of the position in the array and sound level. In order to get these samples I use different applications containing the following line: frame = switch_core_media_bug_get_read_replace_frame(bug); and immediately after insert this code: switch_log_printf( SWITCH_CHANNEL_LOG, SWITCH_LOG_NOTICE, "data[0]=%d\n", ((int16_t *)(frame->data))[0] ); then been rebuilt with the appropriate module and initiating its launch. After that, expect to see on the console different sample values, but it is always the same -1. Someone explain to me why?
