Windows 7 Audio lags behind
 

I have searched the net and found 1000 answers, none of which work.....

I rebooted my computer yesterday and this started. Win 7, lots of RAM and CPU. Worked fine for a few years. When playing a Netflix movie it suddenly lagged the audio about 1-2 seconds behind the video, as in the lips were not synced with the sound. I found this to be occurring in files played locally also, so it is not a Netflix or network related problem.
Did a "scorched earth" fresh install - including formatting the drive, and it is doing it still.

Any assistance from the brain-trust is appreciated.

Thank you.

When you did the fresh install did you all the updates as well?

Prior to did you have auto updates enabled?

Thank you for your reply....

I am doing the updates now. Since it did not occur until I rebooted I am thinking it was one of the updates that caused this. Which is exactly why I don't have "auto update" turned on. My audio driver is the latest from Samsung's website.

Try disabling the hardware acceleration mode.

Does the box have on board video and a video card?

If yes same deal on both?

Here's the funky thing. After a fresh install AND update it appeared to be in sync. Now it is not. I had to roll back the driver to disable acceleration. After doing so the audio lag still remains. Hhmmmm.

Stomach - it's a laptop.

Oh so it's the built in display

One thing I do to quickly eliminate hardware issues is run the box off a Linux live image

Grab an Ubuntu live image, burn a disc or boot from a thumbdrive and run some media

I am no longer "heavy into" the computer thing. Have not been for awhile. I would rather get Win 7 to work for now.

Sorry, not advocating getting rid of Win 7. You boot and run from an Ubuntu CD as a diagnostic.

Completely different OS, drivers etc... so if the problem continues you may be looking at a hardware issue. It's a way to validate you are likely having software problems.

Update - it was the video driver. I did not suspect hardware because it just started after an update/reboot. Generic video driver had not issues but would not let me use the 2 screen option. Finally found a driver that works and allows dual screens. Turning off automatic updates. They cause more problems than they resolve. Thanks all for the input.

Glad you got it sorted.

Auto update is many times nothing more than a veil for beta testing.

Thank you. :)

Back in the day.....

Novell....

You had to update certain files or "THEY" would not support (phone tech support) you....

When you updated as they required, many other services would not load properly. "Public Symbol Errors".

Anyone remember those?

Anyway..they gave me a bad feeling about "updates" years ago.
