Choppy video-sound

[alex1984]

Hi guys

This is my very first attempt at any Linux based OS, and I have to say that I really like it.

I am using an old Acer Aspire One ao751h and the OS looks good and runs quick.

However, I got one issue:

I am trying to watch youtube videos on firefox and they are slightly choppy but watchable (unless in fullscreen, that lags badly), but sound skips alot, making the experience terrible.

Any idea on how this could be fixed?
Please, I am really ignorant in Linux, I can barely use the Terminal and I have no idea on how to fix this.

Firstly, check here: Menu > Settings > Install Drivers to see if there is any driver for the VGA. I think there is a topic somewhere in the forums discussing Flash issues and watching YouTube on low-end machines but I can't find it right now.

Thank you guys!

I tried to find Driver Updates, but it only found stuff for the network card, which works perfectly.


Valtan, I looked at the topic you linked...can I just download that deb file and run it (after I delete the old flash, which if I got it right, is described in the first part of Goldfinger's post)?

[valtam]

Read through the post from the beginning line by line. Follow the instructions first. You may not need flashplugin-legacy after running the first command in the tutorial.

Valtam, I started from the beginning of Goldfinger's post and ran that grep flags command: it does show sse2. Does it mean that I don't need to use the old flash?

Then I tried this SMplayer and I had the same issue: acceptable video performance, but unbearable and choppy audio.

[valtam]

So to quote what it says, "You are looking specifically to see if "sse2" is listed?  If it is NOT listed and you only see "sse", then you need to use an older version of the flashplugin." You say it is not listed, therefore you don't need the older flashplugin.

The next step is to run Menu, System, Create System Report and attach it in your next post.

Thanks Valtam, please bear with me, English is not my native language, so I may be a little "slow" :-[

It's not a particularly powerful computer. Try this, open a terminal and type in: vlc followed by the youtube link.
eg.

Code:

vlc http://www.youtube.com/watch?v=_bmj7tHzXFU

Oh, I know, it's a terrible machine...that's the reason why I decided to remove that Windows xp hog.
Before Linux lite I tried lubuntu and it was the only distro that played videos fine, but it simply did not recognized any wifi, so I was forced to use an Ethernet cable.

I did what you suggested and it opened a vlc window with a Linux lite review...unfortunately, the video doesn't play at all, it appears to stay stuck at 00:00 no matter what I press.

Here's the terminal output:
