1) My understanding : snd_pcm_writei() takes the allocated buffer from applications and passes the buffer beneath to the ASLA library and then to the ALSA driver for rendering Audio.
2) Query 1 : Instead of me allocating the buffer in ALSA application and passing the pointer in snd_pcm_writei, Can ALSA allocate the buffer and give to my application, so that i can copy my data into it.
3) Query 2 : Is there any wayto diirectly get hardware ALSA buffer from the ALSA driver to application so that i can copy PCM data to this buffer directly.
If not, is there any way can we do this ?
Thanks in Advance !
