I've been trying to update my bose software but can't get the setup button to work. I've checked that i'm already on the correct HDMI connected to bose, but it still doesn't go to the UNIFY page when i press the setup button. Could the button be faulty? In addition to that, the soundbar makes a popping/cracking sound whenever it turns on and this has been happening in the last 1 month. I'm not sure if the issue is related to each other but i thought i would mention it. I got this system in 2013. Please could anyone help me? I wish to explore other possible solutions before sending it for repair which is quite costly. Thank you.
