LED and a headphone pin outs
Just had a crazy notion and was wondering the plausibility. Could I plug a wired LED (like my HDD LED) into the pins for headphone jack? Would this give me a volume sensitive LED?

depends on the output level of the headphone jack and the power your led can handle....in most cases you would probably blow the led

if you got an led that would run in the same range as your output then yea it would get brighter as you increased the volume

You would probably damage the soundcard, not the LED, and souncards cost a LOT more.
In principle it should work though, just don't try it IMO.
