If this not have some noise autodetection and auto mute of some inputs, its not what i need..
Why do you need auto-detection and signal switching?
If you're just running straight analog audio (i.e. what comes from a standard stereo audio jack), then all you really need is a mixer. If you're only running a single sound source at a time, then 'muting' the other inputs doesn't matter. There won't be audio from those channels to begin with.
If you really think you need auto-detection and signal switching, you could get something like the Audio Authority 1154A switcher. I own one myself and currently use it for switching between General MIDI sound modules.
But while it features auto detection, but to be honest auto switching isn't that great. There's a slight lag between switching channels, so you'll have a split second of silence before it correctly detects the right channel to switch to. And if any errant audio comes in on another channel, it potentially might switch to that channel disrupting the normal signal. I typically only use it in manual mode, selecting the specific source I want to play at a given time. It's also $220 US versus about $50 for the mixer I posted.
Personally, I'd just go with the mixer.
