Can't fix audio lag

by Ed8r / April 6, 2012 2:58 AM PDT

I just purchased a cNet-recommended notebook, thinking that I could use it to stream HD from Netflix. But after a couple minutes (if that long) the video starts to lag behind the audio and gets progressively worse. I have to click off the HD in order to watch the stream in sync.

The laptop is an HP Pavilion dm1z 11.6" AMD Dual-Core FUSION Processor E-350+AMD Radeon HD 6310M Discrete-Class Graphics, 3GB DDR3 RAM. The TV is a Panasonic VIERA TC-L42U30 42-Inch 1080p 120Hz LCD HDTV.

I am running Chrome on Windows 7. I have a 12Mbps download speed (just slightly under that, for practical purposes).

I have Googled extensively in an attempt to find a simple answer, but so far I can't sort out the solutions to narrow down something that will work for me.

If I need to provide more information about my system, I'll also need to be told how to *find* said info, since I'm pretty much a cyber-luddite.

Thanks you all for any suggestions that might work (aside from trading in this notebook for something else).

You do realize it's not you?

There are too many discussions to link to here but here's one.

Again, why do you think it's you or your machine? We know Netflix is straining at the gills to get thousands of devices working so a little thing like lip sync seems to move to way down the list of problems.

And again, since it did that 10 years ago. *yes, over a decade ago

You begin to wonder if you should reconsider moving to hard media that you can return if they blow it.

But that thread is specifically about a Roku device?

I have an old Roku and had no trouble at all watching HD, but it doesn't pick up subtitles, which I also need.

If this is such a *big* problem, and a KNOWN problem, then why don't even more people report it/ Some people must not be experiencing it, so how did they fix it?

Did you research this?

I offered one of what looks to be many thousands of posts. I think I didn't do a good job here of sharing how pervasive this issue is.

I see the issue on Amazon video at times and then I play it on my PC and that video looks wrong there too. This means the content has an issue. And since Netflix and all these players (devices and companies) have no system to fix this, the problem is there to be discussed.

I was hoping to save you from the wasted time trying to tweak your machine. But it appears I may have not saved you.

I have tried to research

. . . note reference in OP that says "Googled extensively in an attempt to find a simple answer."

But nothing I've found seems to *explain* it knowledgeably. So I wasn't sure it wasn't just something I don't know enough about to fix.

The cause is pretty well known.
by R. Proffitt Forum moderator / April 6, 2012 6:15 AM PDT

The simple answer is there is a problem. I can only guess you are thinking they (Netflix, Amazon) have made something that does not have this issue and the problem is YOUR PC.

Sadly it is rarely your PC.

Again, I'm guessing here you think this technology and content is working properly. Well, it's not.

By asking if you researched this, I was thinking that you would realize this by the sheer volume of complaints.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
