alsa-project/alsa-lib issue #270 was opened from coder0201200:
I am using alsa open source library for my project to read and write audio data.
For that I am using snd_pcm_readi function to read audio data. I am able to read audio data.
But issue is that sometimes it will take so much time to read data.(200-230 msec). Normally this function executed in 1-3 ms that is normal case, but after every 2-4 frames it is taking 200-300 msec. So this is affecting my whole application process.
I have also try to set this call as nonblock with the help of snd_pcm_nonblock function. With that I have observed some improvements but still after 2-3 frames it is taking 100msec time to get a data.
