Hi all, it's my first time on this list and my knowledge about using poll() mutex and thread creation is a bit far away from now, so please, if this list is the wrong place for such a question, could you point me in the right direction? Does anyone can point me a place to find a good exemple of source code for capturing sound with alsa without using callbacks? I'm trying to interface a voice recognition software with the alsa drivers. I have to get audio from alsa convert it and then send to the recognition engine. I've read everywhere that using callback is a bad method to use the alsa drivers. As the recognition software is a server, it needs to be synchronized with my application. And so my main() cannot loop on a endless loop with the snd_pcm_readi() function inside. My first idea was to create a new thread and to let this thread running with a endless loop that do the snd_pcm_readi() and send the buffer to the recognition software. But I 've read the existence of smd_pcm_poll_descriptors() function. For now I not shure was it is for and how to use it properly. What do you think? I'm sorry if my question is a real newbie question, but exemple online are only for playback not capture. Many thanks for all your answers.
