i have no idea what itīs called in english, so iīm just referring to it as system options

looking at the bottom right of my monitor, thereīs a clock and some little symbols ... i got a speaker symbol there
that opens a menu, where i can activate (un-mute) the "mic" playback, and adjust its volume
the result is a nice clean signal without distortion, so iīd say it wonīt hurt

you would only cause damage, if you tried to plug in a 1/4" jack into that 1/8" ... but I guess you knew
and btw, that works without any program, the signalīs pretty much going the direct way to the output
