My wife was frustrated about the sound of the computer. Once the sound comes from the headset, once comed from the loudspeakers. Never from the correct one.

This is a cheap audio switch. It switch not just the sound but the headset microphone to the desktop mic.

Step 1: Requirements

3 stereo slot, for audio
3 mono slot, for microphones
1 two way switch
some two component glue putty
1 old mouse

It's just 510 HUF cca. $2.

Step 2: Assembly

Just make some holes into the mouse, get some glue putty and throw the sockets and the switch into it.

Step 3: Wiring

Solder the wires. The right two socket are the input, the downside four are the headset and loudspeaker output.

Step 4: Installing and Conclusion

Just screw the two side, and put the wires into the AudioSwitch1.0.
I make a sign the mic input, its easier plug.

My wife is full of smiles, at least :)
