not sure if this was just auditory stimuli b from my external environment.
no media codecs. i use headphones...was not using at the time
was just on urbantionary and a forum not doing anything, was reading and had 1 blank page opened. date changed to a new day in calender, 4 minutes later i heard a random chime
sys log shows a cron hourly report. does that cause a sound effect?
was probably from my external environment and sound wave appeared to come from the headphones.
