All, A few days ago I started experiencing some extremely disruptive audio drop-outs while watching videos. Every several minutes, the audio drops for about 0.5-1 second and then resumes. I found later that it is not just with videos, but ALL sources of audio on the computer. I was running Kubuntu as my operating system and had no issues. Frustrated, I decided to try a fresh install of another OS (Xubuntu) to rule it out as a software issue. To my great surprise, the issue was still there! Just this evening I tried installing Debian. Same problem. For the record, these are all clean installs. I am formatting the entire drive each time. On the hardware side of things, the weirdness continues. I have tried audio from the 1/8" analog jack, from USB via my Schiit DAC, and HDMI through the crappy TV speakers. The periodic drop out occurs with ALL outputs! At this point, how does one troubleshoot this issue? It shows up out of the blue as if something screwy happened in software, but multiple clean OS installs do not help. If this was a hardware issue I would have thought only one output would be affected; not all three. I should add that I have noticed a slight hang in the mouse cursor if I happen to be moving it during the drop-out, so something is hanging up and then resuming. Anyone else experienced similar issues with their media computer? I am hoping there is some way to pinpoint this issue so as not to end up throwing money at it. The computer: Shuttle DS-437 single-board fanless computer - Intel Celeron 1.8GHz 8GB RAM 120GB BP4 mSATA SSD A very modest little box, but I have never had issues until just a few days ago. If the hardware simply wasn't capable of what I ask of it, I would think this would have happened from the beginning.
