Hi,

Again starting this thread.

As stated above the underrun problem still remains. Apart from above problem my video and sound going out of sync.

I am using maiplayer to play video on my device. When I start my device the sound start with distortion along with the video but is sync with video but when it switch to another video the video and sound get out of sync.

As stated by Clemens under run occur when " In the general case, an underrun happens when the application has not filled ALSA's sample buffer fast enough and the device is trying to play data that isn't there."

What could be the reason for the video and sound going out of sync. How do I sole the problem.

Let me know If any one need more information.

In the general case, an underrun happens when the application has not
filled ALSA's sample buffer fast enough and the device is trying to
play data that isn't there.
