hi to all firstly. i have 2 computer connected just beside.. but unfortunately i have only just 1 pair of speaker, so i decided to do 1 audio source selector, mean when i dint use 1 computer, i wanna switch the speaker for another 1. i have manage to do the stuff, but the problem is, the output of the sound have "echo" and the sound of singing, is very low.. just can hear the music (very loud) almost like digital d, anything i done mistake?
on side must be out of phase. What that means is that the + and - should be switched. Usually vocals are mic'ed with one mic only. This makes the vocal track usually mono, and mono signals cancel nicely when the sources are out of phase. Musical instuments on the other hand are often recorded stereo and/or are panned to the left or right to provide a soundstage. These components will not cancel well when they meet out of phase. This provides the karaoke effect which can be desireable in certain circumstances. Not here of course.
double check your wiring. Also, you have posted more of a block diagram. if you could post a more detailed schematic i bet the problem will be obvious.
Good luck

oh yea, 1 more, the earth(common) for the jack, i dint solder on the board because i thought it dont needed?
thats the problem, you need to switch the earths over aswell as the signal or it will sound funny and quite likely quite!
This should be easy enough to add on if your switch has enough connections to accomodate 2 more wires to switch.
the signal needs a reference.
