With system up to date
VLC 1.1.9-1ubuntu1.3 (natty-update) => I get the audio sync issue as
described above.
xine is well sync, but just some cracking pb sometime.
Totem 2.32.0 is ok.
I tried the VLC package https://launchpad.net/~bdrung/+archive/ppa
which is not usable at all.
I went back to VLC 1.1.9-1ubuntu1.3 (natty-update)
the issue is back
I installed ALSA drivers from
https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules
version is 2.6.38-11.201108241605
and... everything is just working correctly, still with VLC 1.1.9-1ubuntu1.3.
sync is ok.
If I uninstall alsa driver, the issue is back, re-install corrects it.
my conclusion:
>> There is something wrong with VLC, because with same config, totem and xine
>> are ok
>> There is something wrong in snd-hda-intel ALSA driver too, but it is
>> corrected in last driver.
