I am using Ubuntu 10.10 since its beta release. I had been updating it regularly. Sine the day of up-gradation the audio and video playback is choppy regardless of any format. I waited until 10th of October.

This was not an issue in Lucid. How to resolve this problem.

This really could be any number of problems. It also depends what Video/Audio playback your talking about (Flash, MP4, MP3, etc). Also what kind of Graphics card do you have (or do you even have one, most laptops use integrated graphics). If you could provide more information (like computer model, graphics card, etc) we might be able to help more, but for now I'll give you my best guess.

Flash: Forget about Flash, it sucks! Flash can be a resource hog, however if you want to browse the web it's kind of important to have. What browser are you using? This can make a huge difference as Firefox can have multiple addons that provide Flash support. You can use Adobe's proprietary implementation, or you can use a non-proprietary implementation. I've always had better success with Adobe's versions (but that's just me).

Google Chrome on the other hand comes with Flash support. (Note: Chromium which is the open-source implementation of Chrome does not come with Flash as far as I know). I currently run Chrome on Ubuntu 10.10 and the Flash works amazingly well (and I have a integrated graphics). So far Chrome or Flash has not crashed once.

MP3/MP4/Video/Audio Playback: To ensure you get the best possible playback I would recommend making sure you have FFmpeg. It supports just about every format you'll use (QuickTime, MP4, Real Player, Windows Media Player related codecs, etc).

Once you have this installed these programs/drivers the only thing that will cause choppy playback is your graphics card, or having other programs running that are using your graphics card (Compiz for example).

If you do have an integrated graphics card, increasing the amount of RAM in your system can help. Increasing RAM is also one of the cheapest upgrades you can do. If you have a Desktop, you most likely have a Graphics Card, in which case you can get a new one that will support better video playback.

  • This problem does not seems to be related with GPU. MP3 audio playback is choppy as well. Oct 15, 2010 at 12:42
  • @Shoaib: Technically you don't have a GPU, but I understand what your saying. Have you tried installing FFmpeg?

I was going to simply upvote this, but I did not have the karma =(

Just to set the record straight, the original solution was posted by NightwishFan on the ubuntu forums - thank you NightwishFan

Post #2 here: http://ubuntuforums.org/showthread.php?t=1588889

Workaround for glitchy (crackling, skipping) audio is to open: /etc/pulse/default.pa

Find the line that looks like this and add tsched=0.

load-module module-udev-detect

It should look like this:

load-module module-udev-detect tsched=0

Note: This fixed an issue I had with a soundblaster PCI-e SB1040 card in Ubuntu 11.10 with choppy audio on AMD. The card did not work prior to Ubuntu 11, and was then choppy until this fix with tsched=0 is applied to default.pa.

Save and reboot (or just log out).

Note this will not fix a problem with that specific chipset in the bug report with a muted speaker/headphone. I have no idea where to go with that one. Lidex and I have been trying to figure it out.
