Probably being dense, but not clear to me what problem is: You mean when watching on flash player the sound and the video are out of sync; so that for instance the lips would move before the sound came? If using a KDE or whatever, go to the sound control centre type thing and fiddle for your life.

I don't see what microcode has to do with this.

Flash player is stuttering ? With an intel video card, that is understandable.

no flash ,has nothing to do as i have updated the flash player and i meant that sound and video both have problems like"you play a song and song skips some micro-seconds and then wait for some micro-seconds."

NOTE:This problem occurs but not all time. Every-time i play video-music this happens but if you wait for some time then it will be normal playback.

With the info you provided, it's probably:

1) The intel card is probably not enough.

2) Does this happen through apps other than flash player, so that we can eliminate flash player as the main cause. For example does it happen with mplayer ?

3) It may have something to do with your filesystem and I/O scheduler, which ones are you using ? Try closing all other programs except the media program and see if it still happens. If it does not, change I/O scheduler or filesystem, or maybe try renicing the media player to higher priority.

but the problem just dosnt arises in linux ubuntu but in linux mint. Flash has nothing to do because problem arises also while playing .avi formats
i am not able to understand what is i/o

Can you think of anything that changed between when you were using Ubuntu and now with Mint. You're using the same programs ?

sachinsharma · 02-03-2011, 05:09 AM

yes ,hmmm like video used to stutter in linux mint but not in ubuntu,without any reason.
also mouse becomes un-responsive.I then have to press numlock many times to get it working right

On a simple level might the computer be struggling with the load?

You could try 'top' and see if something is using up a high percentage of the CPU?
