In both Sonic Colors and Xenoblade, I tried to replicate the sound glitches that I heard in your clips. (I couldn't hear them when playing through my regular speakers, so I put on my headset and could hear them in the background)
I heard the sound problems in the DSound and OpenAL backends, but could not in XAudio2 with a latency of 2 for SC. Xenoblade gave some sound glitches on all. See if that works for you. If not, the sound problems go away once you get past the main menu on both.
