I prefer to use the G-Grip with an auxiliary cable to save battery life on my devices. My speaker continues to search for a bluetooth device and will not play via auxiliary cable even when the cable is plugged in. If it is paired, the blue light stays on and it continues to play via bluetooth. If it is not paired, the blue light flashes and it will not play via auxiliary cable. I've tried multiple auxiliary cables. Could the auxiliary jack have gone out?
