I'm looking for an IC/device/... that can switch between sound inputs. Lets say that I play music through audio jack 1, and a GPS is connected to audio jack 2. I'd like the IC/device to lower/kill the audio coming from jack 1 and play the gps sound (being the voice commands by the GPS) from jack 2. When the GPS is done speaking, the music should start playing again after some time.
Is there such a device/switch/ic/...? Does the concept described above have a name?
Thanks in advance.
