That's interesting. Certainly, we've all been cued by the sound of our hard disks that something in our code was wrong or that our computer is up to something unexpected; now that disks are getting quieter and/or replaced by SSDs we lose that important "feature." As code-relevant hardware gets more complex (GPUs and other outboard processors, interaction with robotics or media headsets, etc what-have-you) that sort of hardware-level diagnostic should become more useful, rather than less. Has anyone tried to get this to happen on purpose? E.g., little electrical taps on relevant bus cables, with an audio jack.
