New sound card, same issue. Asus Xonar DX. Shows up in lspci like
'C-Media Electronics Inc CMI8788 [Oxygen HD Audio]'. Uses the
snd_virtuoso driver. The snd_hda_intel module isn't even loaded. The
skips have slightly changed character with the new card, but they still
happen. And still, when
I finally upgraded to 14.04; same exact issue.
One coincidence I noticed and am looking into is that I didn't notice
any stuttering when only 64 bit code was running, but when flash or
steam were running (both of which run some 32 bit code, if I'm not
mistaken), the stuttering began immediately.
And I'll reiterate that when I simply uninstall pulse, but use the same
hardware with alsa, the audio doesn't skip. I don't think it's accurate
to say it's purely the hda driver.

Like I said above, mine now skips much less frequently than every 10
minutes, so I'm skeptical about tweaking any pulse configs at this
point. And since all I did to have it skip less frequently was re-
install pulseaudio and update to all the latest precise packages, it
seems like the issue is so
Results: using "options snd-hda-intel position_fix=1" in /etc/modprobe.d
/alsa-base.conf didn't make the problem go away. Using position_fix=2
made the problem actively worse: the audio literally didn't do anything
but skip. Using "load-module module-udev-detect tsched=0" in
/etc/pulse/default.pa
Ah, ok. That means I've got even more testing to do. Thanks for your
help; I'll report back with my results.

Title:
periodic
I've been trying to reproduce this issue for the last couple weeks, and
I'm somewhat happy to say it happens much, much less frequently now.
Unfortunately, it still happens. It's now on the order of once every
few hours on average instead of once every few minutes, but much less
regularly -- only
