Q: Is it a standard to add integral-microphones into motherboards? I came across a few motherboards that had microphones embedded inside them: I didn't need to plug in any microphone to the computer and could still record myself with programs like Audacity.
Is it some universal standard to add microphones into motherboards? If there is such a standard I assume it was accepted somewhere around the year 2010.
I ask this only out of curiosity (I'm not sure it's the best site to ask this in).

There is not a standard that would cover having a microphone embedded in a motherboard, the only reason it would be included, is because of consumer demand.
