Correct. No setting were changed. I am a computer programmer at my day job so by no means a computer genius, I am well above the average in tech department. I did want to thank everyone for their suggestions, although most implied ignorance at simple volume settings, it turned out to be dirty ports that neither a can of compressed air or a toothbrush scrubbing followed by a vacuum could fix. I brought it to work this morning and blew it out with our commercial air compressor and that did it. I hope this helps the next person at their wits end with the same issue.
