[alsa-devel] Underrun problem in capture and playback application

[Irfan Shaikh]

Hello Developers

                            I have set following configuration for my capture and playback application I am getting lot of UNDERRUN.
How can i avoid buffer underruns.

At a time i am READING "BUFFERSIZE" frames and writing same number of frames in while loop.

SAMPLERATE             44100

PERIODSIZE_CAPTURE             1024
NUMBER_OF_PERIODS_CAPTURE      8

PERIODSIZE_PLAYBACK             512
NUMBER_OF_PERIODS_PLAYBACK      16

NUMBER_OF_CHANNELS     1
SAMPLESIZE             2
FRAMESIZE              (NUMBER_OF_CHANNELS * SAMPLESIZE)

BUFFERSIZE  =     (PERIODSIZE_CAPTURE * NUMBER_OF_PERIODS_CAPTURE)
