Since installing Ubuntu 12.04 LTS on my Core I5 computer, I’ve noticed that I’ve problem with Video/Audio playback on my computer.
It turns out that it only affects computer with Intel-based sound chip. To confirm that you have Intel based audio chip, you need to run this command:
sudo lshw -c multimedia
If Intel chip is present, then you should see something like this at the bottom of the output:
configuration: driver=snd_hda_intel latency=32 resources: irq:16 memory:fe024000-fe027fff
To fix it, you need to add “options snd-had-intel model=generic” at the end of /etc/modprob.d/alsa-base.conf file.
This should fix the problem with choppy/laggy sound while playing video.
