I am using a raspberry pi 2, with the latest version of raspbian. It is part of the Ultimate Kit by Cana Kits. It fails to output audio in all cases. I have tried both HDMI and the 3.5mm port. The HDMI has no sound at all. The 3.5 port makes clicking sounds while launching the GUI, and has no sound afterwards. I tried the HDMI that was included in the kit, and another HDMI that I normally use for my Xbox. The cables were in 2 different input ports on my TV. Everything else works perfectly, only the audio has a problem. Are there any known causes or solutions?
