That is prolly the same CPU power saving bug that has bothered VLC for years. Currently power saving things like Cool and Quiet etc. don't notice that VLC wants CPU cycles. So CPU frequency is kept too slow, setting the Windows power mode to full power should solve it.
This helped! Thanks!
Same problem: The audio was stuttering every 8-13 seconds (didn't count really).
The power plan didn't helped directly, but changing the settings of the "power saving thing" EPU-6 Engine (a tool for ASUS P5Q Series Motherboard) to High Performance (0% over-/underclocking, default fan speed, etc.) helped. Before, it was on -1% of CPU frequency. Therefore, I tested the 3% of CPU frequency overclocked setting and it happened to work fine without stuttering.
I also noticed that the stuttering lasted longer when the file caching value was higher.
On lower caching values it lasted shorter, but on value 0 it was just like 300ms.
Nevertheless, here are debug messages before and after changing the CPU frequency (the comments are edits by me).

It's working, but I'm still wondering about the warnings, because when I disable audio there is no warning at all.
After all, the warnings doesn't appear as often as before.
