Comment 32 for bug 874535

Side note: There might actually a better solution in newer kernels: if you install the daily DKMS package ( https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS ) you will get this too.

Then edit /etc/modprobe.d/alsa-base.conf and add this line:

options snd-hda-intel jackpoll_ms=250

..then reboot and test. In case the sound card is not the first hda intel sound card, you might need to add more, like this:

options snd-hda-intel jackpoll_ms=0,250

or

options snd-hda-intel jackpoll_ms=0,0,250

...depending on which card you want to change.
