I have a Sony HT-CT150 sound system that's subwoofer acts as a hub for all my HDMI cord inputs, so basically a cord from the TV to the sub, and then cords from the sub to everything else. I recently bought a Red/White to AUX cord that can be plugged into the back of the subwoofer and used to play music from my phone, here's where the problem comes in, I want to somehow overlap the audio coming from my phone with the audio coming from the HDMI of the Ps3, but apparently I can only use either the CD player input to listen to the phone, or the Blu-Ray input for the Ps3 at a single time, is there any way for me to combine/overlap the audio of these two inputs? Some sort of workaround or adapter? I just want to listen to my own music instead of infinitely looping game music.
