Remove Display Driver Improves Audio Quality Greatly!

A few months ago I removed the video driver from my PC in an attempt to reduce stuttering via DLNA. I run my PC headless. Removing the driver did reduce latency (as measured by latencymon). In the end, I don't think it made much of a change in the stuttering and I can't comment on the effect on the sound quality.

In my particular case I think the issue is more related to my DLNA renderer (an Onkyo AVR). I only wanted to point out that the video driver was contributing to system latency which as I understand it, can affect the playback of audio.
