So, I really don't have much idea why it is being tried to set to the boundary value. Here is the simplified version of the whole code (for only setting the software parameters). I am also trying to understand what it really does. bool softwareParameters(void) { snd_pcm_sw_params_malloc(¶ms); snd_pcm_sw_params_current(pHandle, params); snd_pcm_sw_params_set_avail_min(pHandle, params,period); snd_pcm_sw_params_get_boundary(params, &boundary); snd_pcm_sw_params_set_start_threshold(pHandle, params, 0.50 * buffSize); snd_pcm_sw_params_get_start_threshold(params, &th); snd_pcm_sw_params_set_stop_threshold(pHandle, params, boundary); snd_pcm_sw_params_get_stop_threshold(params, &th); snd_pcm_sw_params_set_silence_size(pHandle, params, 0); snd_pcm_sw_params_get_silence_size(params, &th); snd_pcm_sw_params_set_silence_threshold(pHandle, params, boundary); snd_pcm_sw_params_get_silence_threshold(params, &th); snd_pcm_sw_params (pHandle, params); snd_pcm_sw_params_free(params); return (true); } I removed all the loggings and error controls to make it easier to read. ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
