ADG715BRU switch for audio application

I have the ADG715BRU analog switch that I want to use as an audio switch. There are 7 inputs channels and one output. I would like to switch the desired input to the one output. I connected 7 outputs of the ADG715 together to make a single output. However, When I tested the design in this manner, there is always channel interference, meaning the channel isolation is poor. Therefore, I would like to know if we can use the ADG715 as a 7 to 1 (or 8 to 1) switch in audio application by connecting the outputs together with good isolation between channels.
