Thread: Question about auto switching audio

Ok let me see if I can describe this. My setup would consist of a hu, pc, amp.

What I would like to do is have the audio out of hu and pc go to some kind of switching system then to the amp. It would allow the hu to play until it sences a signal from the pc at the point it would stop the signal from the hu from going to the amp and send the pc signal to the amp. So if I was listening to the radio and using gps and the gps wanted to tell me to turn it would kill the hu, pc would announce the turn. When the pc was done talking it would then swith back to the hu. Is there already a switching system like this or could it be easily built and information would be appeciated.

Thanks

Paul
