I am trying to set my alsa buffer size as 1024*8. But my playback device is not able to set to requested ALSA buffer size.
snd_pcm_hw_params_set_periods(handle, params, 8, 0);
snd_pcm_hw_params_set_period_size(handle, params, 1024, 0);
retVal=snd_pcm_hw_params_set_buffer_size_near(handle, params, &frames1);
(snd_pcm_uframes_t *) &val);
==============>>>>>>> buffer size = 8192 frames
==============>>>>>>> buffer size = 1325 frames
Return value for above APIs is coming as zero. but still i am unable to get expected result. Is there any other forcible way to do the above.
