Hi, snd_pcm_uframes_t boundary; snd_pcm_sw_params_get_boundary(params, &boundary); I see a huge number like "7944349742681554944" in boundary after this call. Is this normal? I see exactly the same huge number when I use this boundary to set the threshold as in the following code part: snd_pcm_sw_params_set_stop_threshold(handlePlayback, params, boundary); snd_pcm_sw_params_get_stop_threshold(params, &threshold); So the returning threshold value is again "7944349742681554944". Can you comment on the correctness of these values? ------------------------------------------------------------------------------ October Webinars: Code for Performance Free Intel webinars can help you accelerate application performance.
