Installed 11.10 on two systems - a desktop and a laptop. On the desktop the sound is OK, while on the laptop, I get horrible lags and skips on all audio. If playing a movie and the soundcard is enabled, the video becomes choppy too.
Tried both an upgraded system (from 11.04) and a clean install, same problem.
The sound is *always* choppy, I get bursts of sound for about 1/2 second then maybe 1 second of silence. The "bursts of sound" appear to come in random order, too.
The whole system is totally unable to perform any multimedia task as is now (i.e. playing music, playing videos, playing games).
Sound card is a n ExpressCard card:
[code]cristian@cristian-laptop:~$ lspci | grep Audio
06:00.0 PCI bridge: Creative Labs [SB X-Fi Xtreme Audio] CA0110-IBG PCI to PCIe Bridge
07:00.0 Audio device: Creative Labs [SB X-Fi Xtreme Audio] CA0110-IBG
[/code]
I attached the pulseaudio log taken during a choppy audio playback.
Restricted drivers in use:
Broadcom STA wireless driver,
nVidia accelerated graphics driver.
If any further info is needed I'll post here.

Thanks for your bug report. I'll target this to alsa-driver for now so we can get an apport hook, but this may be suited to pulseaudio or possibly the kernel as well. In any case, could you please run the following command in a terminal on your laptop and then change the status of this bug back to new:
apport-collect 887913
That will add some more system information and log files to your report so that someone more familiar with debugging sound issues can diagnose the problem. Thanks in advance.
